أَخْبَرَنَا عَمْرُو بْنُ عَلِيٍّ، وَمُحَمَّدُ بْنُ الْمُثَنَّى، وَيَعْقُوبُ بْنُ إِبْرَاهِيمَ، - وَاللَّفْظُ لَهُ - قَالُوا حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ، قَالَ حَدَّثَنَا جَعْفَرُ بْنُ مُحَمَّدٍ، قَالَ حَدَّثَنِي أَبِي قَالَ، أَتَيْنَا جَابِرَ بْنَ عَبْدِ اللَّهِ فَسَأَلْنَاهُ عَنْ حَجَّةِ الْوَدَاعِ، فَحَدَّثَنَا أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم خَرَجَ لِخَمْسٍ بَقِينَ مِنْ ذِي الْقَعْدَةِ . وَخَرَجْنَا مَعَهُ حَتَّى إِذَا أَتَى ذَا الْحُلَيْفَةِ وَلَدَتْ أَسْمَاءُ بِنْتُ عُمَيْسٍ مُحَمَّدَ بْنَ أَبِي بَكْرٍ فَأَرْسَلَتْ إِلَى رَسُولِ اللَّهِ صلى الله عليه وسلم كَيْفَ أَصْنَعُ فَقَالَ " اغْتَسِلِي ثُمَّ اسْتَثْفِرِي ثُمَّ أَهِلِّي " .
Ja'far bin Muhammad said: "My father told me: 'We came to Jabir bin 'Abdullah and asked him about the Hajj of the Prophet (PBUH). He narrated; "The Messenger of Allah (PBUH) set out when there were five (days) remaining in Dhul-Qa'dah, and we set out with him. When he came to Dhul-Hulaifah, Asma' bint 'Umais gave birth to Muhammad bin Abi Bakr. She sent word to the Messenger of Allah (PBUH) asking what he should do. He said: 'Perform Ghusl, bind yourself with a cloth then begin (the Talbiyah for Ihram).'" Translation Not Available
