Sunan Abi Dawud Book 2, Hadith 205
Anas said that the Prophet (ﷺ) appointed Ibn Umm Maktum as substitute to lead the people in prayer, and he was blind.
The obligatory prayer is essential behind every Muslim, pious or impious, even if he has committed a sins.
Malik b. al-Huwairith came to this place of prayer of ours, and the iqamah for prayer was called. We said to him: Come forward and lead the prayer. He said to us: Put one of your own men forward to lead you in prayer. I heard the Messenger of Allah(ﷺ) say: If anyone visits people, he should not lead them in prayer, but some person of them should lead the prayer.
