Mishkat al-Masabih 4 Prayer كتاب الصلاة 538

وَعَنْ أَنَسٍ قَالَ: اسْتَخْلَفَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ ابْنَ أُمِّ مَكْتُومٍ يَؤُمُّ النَّاس وَهُوَ أعمى. رَوَاهُ أَبُو دَاوُد

Anas said that God’s Messenger appointed Ibn Umm Maktum as substitute to lead the people in prayer, and he was blind. Abu Dawud transmitted it.
