Narrated Anas (RA):

The Prophet (ﷺ) appointed Ibn Umm Maktum (RA) to lead the people in prayer in his absence and he [Ibn Umm Maktum (RA)] was blind. [Reported by Ahmad and Abu Dawud].

وَعَنْ أَنَسٍ رَضِيَ اَللَّهُ عَنْهُ; { أَنَّ اَلنَّبِيَّ ‏- صلى الله عليه وسلم ‏-اِسْتَخْلَفَ اِبْنَ أُمِّ مَكْتُومٍ, يَؤُمُّ اَلنَّاسَ, وَهُوَ أَعْمَى } رَوَاهُ أَحْمَدُ, وَأَبُو دَاوُد َ [1]‏ .‏
