حَدَّثَنَا مُحَمَّدُ بْنُ مَنْصُورٍ الطُّوسِيُّ، حَدَّثَنَا يَعْقُوبُ، حَدَّثَنَا أَبِي، عَنِ ابْنِ إِسْحَاقَ، حَدَّثَنِي نَافِعٌ، عَنِ ابْنِ عُمَرَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم حِينَ أَقْبَلَ مِنْ حَجَّتِهِ دَخَلَ الْمَدِينَةَ فَأَنَاخَ عَلَى بَابِ مَسْجِدِهِ ثُمَّ دَخَلَهُ فَرَكَعَ فِيهِ رَكْعَتَيْنِ ثُمَّ انْصَرَفَ إِلَى بَيْتِهِ ‏.‏ قَالَ نَافِعٌ فَكَانَ ابْنُ عُمَرَ كَذَلِكَ يَصْنَعُ ‏.‏

Narrated Abdullah ibn Umar: When the Messenger of Allah (PBUH) arrived from his hajj, he entered Medina, and made (his camel) kneel down at the gate of his mosque; and he entered it and offered two rak'ahs of prayer; he then returned to his home. Nafi' said: Ibn Umar also used to do so. Translation Not Available
