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)

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)
