“I heard abu Ja’far (a.s.), say, ‘Every mistake in Salah (prayer) is dropped thereby except that Allah, the Most High, completes it with optional prayers. The first item of deeds with which one is judged is Salah (prayer). If Salah (prayer) is accepted, other deeds are also accepted. If Salah (prayer) is raised in the beginning of its designated time, it comes to the person prayed it all white and radiant, saying, “You preserved me, may Allah protect you.” If Salah (prayer) is raised in other times without observance of the rules about it Salah (prayer) returns back to the person who has performed it, all black and dark, saying, “You wasted me away, may Allah lay you waste.’”
