“I heard abu Ja‘far (a.s.), say while speaking to people in Makkah, ‘One day the Messenger of Allah completed his Salah (prayer) of the morning and sat in the Masjid with his companions until sunrise. Thereafter, people one by one left the Masjid except two men, one from the people of Ansar and the other from Thaqif. The Messenger of Allah then said to them, “I understand you need to ask me questions. You may ask if you like and I will answer. If you like, I can tell you what your questions are before you ask. If you wish, you may ask me.” They said, “Please inform us before we ask you our questions; it is more enlightening, frees us from doubts and strengthens our belief more.” The Messenger of Allah then said, “You, gentleman from Thaqif, have come to ask me about your Wudu’ and Salah (prayer) regarding what is good for you in them. You should keep in mind that when you place your hand in your water container and say ‘In the name of Allah’ the sins that your hands may have committed scatter away from you. The sins that your eyes and mouth may have committed scatter away from you when you wash your face. When you wash your arms to your elbows, the sins from your left and right scatter away from you. When you wipe your head and feet the sins into which you may have walked scatter away from you. This is what you gain from your Wudu’.’””
