حَدَّثَنَا مُحَمَّدُ بْنُ عُبَيْدٍ حَدَّثَنَا عُبَيْدِ اللَّهِ عَنْ نَافِعٍ عَنِ ابْنِ عُمَرَ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ كَانَ إِذَا أَدْخَلَ رِجْلَهُ فِي الْغَرْزِ وَاسْتَوَتْ بِهِ نَاقَتُهُ قَائِمَةً أَهَلَّ مِنْ مَسْجِدِ ذِي الْحُلَيْفَةِ
مسند امام احمد بن حنبل · Hadith 4842
It was narrated from Ibn 'Umar (RA) that when the Messenger of Allah (PBUH) put his foot in the stirrup and his she-camel rose with him, he started reciting the Talbiyah (after entering ihram) from the mosque of Dhu'l-Hulayfah.
