Abu al-Malih narrates from his father: We were performing prayer behind the Prophet Muhammad (peace be upon him), when a blind man came and fell into a pit, that is, the well which was present in the mosque. Some of the people behind the Prophet (peace be upon him) laughed, so the Prophet (peace be upon him) ordered those who laughed to perform ablution again and repeat the prayer. The narrator of this hadith, Hasan bin Dinar, is considered abandoned in hadith narration. This narration has also been transmitted by Abdur Rahman bin Amr, who is also considered abandoned in hadith narration. He narrated this report from Salam, from Qatadah, from Abu al-Aliyah, from our master Anas bin Malik (may Allah be pleased with him).
