Sahih Bukhari Volume 1, Book 10, Hadith 841

قَالَ سَمِعْتُ عِتْبَانَ بْنَ مَالِكٍ الأَنْصَارِيَّ، ثُمَّ أَحَدَ بَنِي سَالِمٍ قَالَ كُنْتُ أُصَلِّي لِقَوْمِي بَنِي سَالِمٍ، فَأَتَيْتُ النَّبِيَّ صلى الله عليه وسلم فَقُلْتُ إِنِّي أَنْكَرْتُ بَصَرِي، وَإِنَّ السُّيُولَ تَحُولُ بَيْنِي وَبَيْنَ مَسْجِدِ قَوْمِي، فَلَوَدِدْتُ أَنَّكَ جِئْتَ فَصَلَّيْتَ فِي بَيْتِي مَكَانًا، حَتَّى أَتَّخِذَهُ مَسْجِدًا فَقَالَ ‏"‏ أَفْعَلُ إِنْ شَاءَ اللَّهُ ‏"‏‏.‏ فَغَدَا عَلَىَّ رَسُولُ اللَّهِ صلى الله عليه وسلم وَأَبُو بَكْرٍ مَعَهُ بَعْدَ مَا اشْتَدَّ النَّهَارُ، فَاسْتَأْذَنَ النَّبِيُّ صلى الله عليه وسلم فَأَذِنْتُ لَهُ، فَلَمْ يَجْلِسْ حَتَّى قَالَ ‏"‏ أَيْنَ تُحِبُّ أَنْ أُصَلِّيَ مِنْ بَيْتِكَ ‏"‏‏.‏ فَأَشَارَ إِلَيْهِ مِنَ الْمَكَانِ الَّذِي أَحَبَّ أَنْ يُصَلِّيَ فِيهِ، فَقَامَ فَصَفَفْنَا خَلْفَهُ ثُمَّ سَلَّمَ، وَسَلَّمْنَا حِينَ سَلَّمَ‏.‏

he said:I heard from Itban bin Malik Al-Ansari, who was one from Bani Salim, saying, "I used to lead my tribe of Bani Salim in prayer. Once I went to the Prophet and said to him, 'I have weak eye-sight and at times the rainwater flood intervenes between me and the mosque of my tribe and I wish that you would come to my house and pray at some place so that I could take that place as a place for praying (mosque). He said, "Allah willing, I shall do that." Next day Allah's Apostle along with Abu Bakr, came to my house after the sun had risen high and he asked permission to enter. I gave him permission, but he didn't sit till he said to me, "Where do you want me to pray in your house?" I pointed to a place in the house where I wanted him to pray. So he stood up for the prayer and we aligned behind him. He completed the prayer with Taslim and we did the same simultaneously."
