Yahya related to me from Malik from Hisham ibn Urwa from his father that the Messenger of Allah ﷺ used to pray two rakas in the mosque at Dhu'l-Hulayfa, and then, when he had got on to his camel and it had stood up, he would begin doing talbiya.

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ هِشَامِ بْنِ عُرْوَةَ، عَنْ أَبِيهِ، أَنَّ رَسُولَ اللَّهِ ﷺ كَانَ يُصَلِّي فِي مَسْجِدِ ذِي الْحُلَيْفَةِ رَكْعَتَيْنِ فَإِذَا اسْتَوَتْ بِهِ رَاحِلَتُهُ أَهَلَّ .
