Sayyiduna Abu Hurairah (may Allah be pleased with him) says that I went to Sayyidah Aisha (may Allah be pleased with her), and I heard her saying that when the Messenger of Allah (peace and blessings of Allah be upon him) would come out of the toilet, he would say «‏‏‏‏غُفْرَانَكَ» ‏‏‏‏ "O Allah, I seek Your forgiveness." (The Imam says) Muhammad bin Aslam narrated to us from Ubaidullah bin Musa, and he narrated from Isra'il in the same manner.
