Virtue of Wudu (Ablution)

Allah SWT says: O you who believe! When you rise to (perform) Salat, wash your faces and your fore arms to the elbows, and wipe over your heads and wash your feet to (including) the ankles.
Al-Maidah 5:6

Allah SWT says: And Allah loves those who purify themselves. (Tawbah 9:108)

Abu Hurairah RA narrates: I heard Rasulullah SAW saying: My Ummah will called on the Day of Resurrection with their limbs and faces shining from traces of Wudu. So whoever amongst you can increase the area of his radiance should do so (i.e. by performing Wudu regularly). (Bukhari)
Note: Meaning that Wudu should be performed throughly with such care that no part of the skin should remain dry. (Mazahir Haque)

Uthman ibne Affan RA narrates that Rasulullah SAW said: Anyone who performs Wudu and excellently (meaning thereby to carefully observe all the etiquettes), his sins will come out from his body, even coming out from under his nails. (Muslim)
Note: The opinion of majority of the scholars is that minor sins, are forgiven by Allah through Wudu , Salat and other forms of worship. The major sins, are forgiven by Istigfar (seeking forgiveness) and Taubah (turning towards Allah with repentance). However, Allah by His bountiful Grace, may even forgive the major sins by virtue of above deeds (Nawawi)

virtue of salat in jammah congregation

Allah SWT says: And establish salat and give Zakat; and bow with those who bow in worship (i.e. pray in congregation) (al-baqarah 2:43)

Abu Hurarirah RA narrated that Nabi SAW said: The muadhdhin will receive forgiveness to the distance to which his voice reaches. All living and non-living things shall bear witness for him on the Day of Resurrection. He, who attends salat in congregation, for him is written the reward of twenty five salat, and it becomes an atonement for his sins between two Salat. (Abu Dawud)
Note: According to some Scholars the reward of twenty-five Salat is for the muadhdhin, and he gets forgiveness of his sins from the previous Adhan to this Adhan. (Badhl-ul-Majhud)

Ibne Umar RA narrates that Nabi SAW said: He who calls the Adhan for twelve years, Paradise is guaranteed for him and sixty blessings will be recorded for every adhan, thirty blessings will be recorded for every Iqamah. (Mustadrak Hakim)

Rasulullah's Journey to Taif

For nine years, since his selection by Allah for His mission, Rasulullah SAW had been delivering the message of Allah in Makkah and making all out efforts to guide and reform his community. Excepting a few persons who had either embraced Islam or who helped him, though not accepting his creed, all the rest in Makkah left no stone unturned in persecuting and deriding him and his followers. His uncle Abu Talib was one of those good-hearted people who helped him, in spite of his not entering the fold of Islam. The following years, on the death of Abu Talib, the Quresh got a free hand and therefore accelerated their sinister activities without check and hindrance. At Taif, the second biggest town of Hijaz, there lived Banu Thaqif-a clan strong in number. Rasulullah SAW left for Taif in the hope of winning them over to Islam, thus giving quarter to Muslim from the persecution of the Quresh, and also establishing a base for the future propagation of Islam. On reaching Taif he visited the three chieftains of the clan separately, and placed before each of them the message of Allah, and called upon him to stand by his (Prophet's) side.Instead of accepting his message, they refused even to listen to him and, notwithstanding the proverbial Arab hospitality, each of them treated him most contemptuously and rudely. They plainly told him that they did not like his stay in their town. The Prophet SAW had expected a civil, even a cordial treatment and due courtesy in speech from them, as they were the heads of the clan. But one of them sneered: "Hey, Allah has made you a Prophet!", The other exclaimed with derision : "Could Allah not lay His hand on anyone else, other than you, to make His Prophet?",The third one gibed at Him: "I do not want to talk to you, for if you are in fact a Prophet, then to oppose you is to invite trouble, and if you, only pretend to be one, why should i talk with an imposter?"
Rasulullah SAW, who was a rock of steadfastness and perseverance, did not lose heart over the rebuft from the cheftains, and tried to approach the common people; but nobody would listen to him. Instead they asked him to clear off from their town and go wherever else he liked. When he realised that further efforts were in vain, he decided to leave the town. But they would not let him depart in peace, and set the street urchins after him, to hiss, to hoot, to jeer at, and to stone him. He was so much pelted with stones that his body was covered with blood, and shoes were clogged to his ffet. He left the town in this woeful plight. When he was far out of the town, and safe from rabble, he prayed to Allah thus: "o, my Allah! To Thee I complain of the feebleness of my strength, of my lack of resources and my being unimportant in the eyes of people. O, most Merciful of all those capable of showing mercy! Thou art the Lord of the weak, and Thou art my own Lord. To whom art Thou entrust me; to an unsympathetic foe who should sullenly frown at me, or to an alien to whom Thou has given control over my affair? Not in the least do I care for anything except that I may Thy protection for myself. I seek shelter in Your light-the light which iluminates the Heavens and dispels all sort of darkness, and which controls all affairs in this world as well as in the Hereafter. Mat it never be that I should incur Thy wrath, or that Thou should be displeased with me. I must remove the cause of Thy displeasure till Thou art pleased. There is no strength nor power but through Thee." The heaven were moved by the prayer, and Jirail AS appaered before Rasulullah SAW, greeting him with Assalamo alaikum and said: "Allah knows all that has passed between you and these people. He has deputed an angel incharge of the mountains to be at your command." Saying this, Jibrail AS ushered the angel before Rasulullah. The angel greeted Rasulullah SAW and said: "O, Prophet of Allah! I am at your service. If you wish, I can cause the mountains overlooking this town on both sides to collide with each other, so that all the people therein would be crushed to death, or you may suggest any other punishment for them." The merciful and noble Prophet SAW said: "Even if these people do not accept Islam, I do hope from Allah that there will be persons from among their progeny who would worship Allah and serve His cause." Behold the conduct of our noble Prophet SAW, whom we profess to follow! We get so much irritated over a little trouble or a mere abuse from somebody that we kept on torturing and taking our revenge throughout our lives in every possible manner. Does it become people who claim to follow the magnanimous prophet SAW? Look, even after so much suffering at the hands of the Taif mob, he neither curses them nor does he work for any revenge, even when he has the full opportunity to do so.

virtue of salat

Allah SWT says: Verily Salat restrains (oneself) from immorality and all that is forbidden. (al-ankabut 29:45)

Allah SWT says: Indeed, those who believe and do righteous deeds, and establish Salat and give Zakat; their reward is with their Rabb (Sustainer &Cherisher), and neither fear shall come upon them, nor will they grieve (al-baqarah 2:277)

Allah SWT said to His prophet SAW: Perform salat from midday till the darkness of the night (i.e. Zuhr, 'Asr, Maghrib and 'Isha prayers) and recite the Quran in the early dawn (i.e. the morning prayer). Verily, the recitation of the Quran in the early dawn is witnessed (by angels) (al-isra 17:78)

Allah SWT says: O you who believe! When the Adhan is called for the prayer on the day of Jumu'ah (Friday), then hasten to the remembrance of Allah and leave all trading (and other engagements) aside. That is better for you, if you but knew. (al-jumu'ah 62:9)

Abdullah Ibne Umar RA narrates that Rasulullah SAW said: Islam has been built upon five pillar: 1) To testify that none is worthy of worship but Allah and that Muhammad is the Messenger of Allah, 2) to establish Salat, 3) to give zakat, 4) to perform Hajj, and 5) to fast (Saum) in the Ramadhan. (bukhari)

Jabir ibne Umar RA narrates that Nabi SAW said: The key to paradise is Salat and the key to Salat is Wudu. (Musnad Ahmad)

virtues of kalimah Lailaha illallah

Virtues of Kalimah Tayyibah

Abu Hurairah R.A narrates that Rasulullah SAW said: Iman (faith) has more than seventy branches; the superiormost one is saying La ilaha illallah (there is none worthy worship except Allah); and the inferior most is the removal of an obstacles from the way; and Haya is a branch of iman. (Muslim)

Note: The essence of Haya is that it restrains a man from evil and prevents a man from neglecting the obligations that he owes to others. (Riyad-us-salihin)

Abu Bakr RA narrates that Rasulullah SAW said: He who accepts from me the Kalimah, which I presented to my uncle (Abu Talib at the time of his death) and he rejected it, this will be means for his salvations. (Musnad Ahmad)

Abu Hurairah RA narrates that Rasulullah SAW said: Whenever a slave (of Allah) says La ilaha illallah sincerely, the doors of the skies are opened (for it to ascend) until it reaches the Arsh (Throne of Allah, and is readily accepted) provided he abstains from major sins. (Tirmidhi)

Note: To say sincerely means that it is free from pretence and hypocrisy. Abstaining from major sins ensures its rapid acceptance, and even if it recited without abstaining from major sins, it is still beneficial and rewarding. (Mirqat-ul-Mafatih)

Abu Hurairah RA narrates that Rasulullah SAW said: He who says La ilaha illallah, it shall benefit him (be means for salvation) though before that he may be afflicted by what (punishment) is to befall him. (Bazzar,Tabarani,Targhib)

Umar RA narrates Nabi SAW said: O son of Khattab! Go and announce amongst the people that indeed none shall enter paradise except the Mu’minun (believers). (Muslim)

Anas RA narrates: I heard Nabi SAW saying: When the Day of Resurrection will take place, I will be allowed intercession, so I will say: O my Rabb! Send to paradise whoever had in their hearts a mustard seed of Iman (Allah SWT will accept my intercession), so they will enter Paradise. Then, I will say: Send to Paradise whoever had in his heart the smallest particle (of Iman). (Bukhari)
