Narrated `Itban bin Malik Al-Ansari:
حَدَّثَنَا مُعَاذُ بْنُ أَسَدٍ ، أَخْبَرَنَا عَبْدُ اللَّهِ ، أَخْبَرَنَا مَعْمَرٌ ، عَنِ الزُّهْرِيِّ ، قَالَ أَخْبَرَنِي مَحْمُودُ بْنُ الرَّبِيعِ ، قَالَ سَمِعْتُ عِتْبَانَ بْنَ مَالِكٍ الأَنْصَارِيَّ ، قَالَ اسْتَأْذَنَ النَّبِيُّ صلى الله عليه وسلم فَأَذِنْتُ لَهُ فَقَالَ " أَيْنَ تُحِبُّ أَنْ أُصَلِّيَ مِنْ بَيْتِكَ ". فَأَشَرْتُ لَهُ إِلَى الْمَكَانِ الَّذِي أُحِبُّ، فَقَامَ وَصَفَفْنَا خَلْفَهُ ثُمَّ سَلَّمَ وَسَلَّمْنَا.
The Prophet (came to my house and) asked permission for entering and I allowed him. He asked, "Where do you like me to pray in your house?" I pointed to a place which I liked. He stood up for prayer and we aligned behind him and he finished the prayer with Taslim and we did the same.
