"I said to Ibn 'Umar: 'I saw you begin the Talbiyah when your she-camel stood up with you. He said: "The Messenger of Allah used to begin the Talbiyah when his she-camel stood up with him." (Using translation from Nasāʾī 2760)
قُلْتُ لِابْنِ عُمَرَ رَأَيْتُكَ تُهِلُّ إِذَا اسْتَوَتْ بِكَ نَاقَتُكَ قَالَ إِنَّ رَسُولَ اللهِ ﷺ كَانَ «يُهِلُّ إِذَا اسْتَوَتْ بِهِ نَاقَتُهُ وَانْبَعَثَتْ»
