It was narrated from HIsham bin Urwah, from his father, from Umm Salamah, that she said:
"O Messenger of Allah, by Allah! I have not performed the Farewell Tawaf." The Prophet said: "When the Iqamah is said for prayer, perform Tawaf on your camel behind the people." Urwah did not hear from Umm Salamah.
أَخْبَرَنَا مُحَمَّدُ بْنُ آدَمَ، عَنْ عَبْدَةَ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، عَنْ أُمِّ سَلَمَةَ، قَالَتْ يا رَسُولَ اللَّهِ وَاللَّهِ مَا طُفْتُ طَوَافَ الْخُرُوجِ ‏.‏ فَقَالَ النَّبِيُّ صلى الله عليه وسلم ‏ "‏ إِذَا أُقِيمَتِ الصَّلاَةُ فَطُوفِي عَلَى بَعِيرِكِ مِنْ وَرَاءِ النَّاسِ ‏"‏ ‏.‏ عُرْوَةُ لَمْ يَسْمَعْهُ مِنْ أُمِّ سَلَمَةَ ‏.‏
