حَدَّثَنَا إِسْمَاعِيلُ ، قَالَ حَدَّثَنِي مَالِكٌ ، عَنِ ابْنِ شِهَابٍ ، عَنْ مَحْمُودِ بْنِ الرَّبِيعِ الأَنْصَارِيِّ ، أَنَّ عِتْبَانَ بْنَ مَالِكٍ ، كَانَ يَؤُمُّ قَوْمَهُ وَهْوَ أَعْمَى، وَأَنَّهُ قَالَ لِرَسُولِ اللَّهِ صلى الله عليه وسلم يَا رَسُولَ اللَّهِ، إِنَّهَا تَكُونُ الظُّلْمَةُ وَالسَّيْلُ وَأَنَا رَجُلٌ ضَرِيرُ الْبَصَرِ، فَصَلِّ يَا رَسُولَ اللَّهِ فِي بَيْتِي مَكَانًا أَتَّخِذُهُ مُصَلًّى، فَجَاءَهُ رَسُولُ اللَّهِ صلى الله عليه وسلم فَقَالَ " أَيْنَ تُحِبُّ أَنْ أُصَلِّيَ ". فَأَشَارَ إِلَى مَكَانٍ مِنَ الْبَيْتِ، فَصَلَّى فِيهِ رَسُولُ اللَّهِ صلى الله عليه وسلم.
`Itban bin Malik used to lead his people (tribe) in prayer and was a blind man, he said to Allah's Apostle , "O Allah's Messenger (ﷺ)! At times it is dark and flood water is flowing (in the valley) and I am blind man, so please pray at a place in my house so that I can take it as a Musalla (praying place)." So Allah's Messenger (ﷺ) went to his house and said, "Where do you like me to pray?" 'Itban pointed to a place in his house and Allah's Messenger (ﷺ), offered the prayer there.
