Sayyiduna Hasan al-Basri narrates: Once the Prophet Muhammad (peace be upon him) was performing prayer, during which a man came whose eyesight was weak (the narrator is unsure) or he was blind. He fell into a well, and some people laughed. The Prophet Muhammad (peace be upon him) ordered those who laughed to repeat their prayer and perform ablution. The narrator states: I mentioned this narration to Hafs bin Salman, and he said: "I narrated this hadith to Hasan al-Basri on the authority of Hafsa (bint Sirin), and the correct version is that this narration is transmitted as a mursal narration from Hasan al-Basri."
