Sahih al-Bukhari · Book 64: Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi) · The letter of the Prophet (saws) to Kisra (Khosrau) and Qaiser (Caesar)
Narrated As-Saib:
حَدَّثَنَا عَبْدُ اللَّهِ بْنُ مُحَمَّدٍ ، حَدَّثَنَا سُفْيَانُ ، عَنِ الزُّهْرِيِّ ، عَنِ السَّائِبِ ، أَذْكُرُ أَنِّي خَرَجْتُ مَعَ الصِّبْيَانِ نَتَلَقَّى النَّبِيَّ صلى الله عليه وسلم إِلَى ثَنِيَّةِ الْوَدَاعِ مَقْدَمَهُ مِنْ غَزْوَةِ تَبُوكَ.
I remember I went out with the boys to Thaniyat-ul-Wada` to receive the Prophet (ﷺ) when he returned from the Ghazwa of Tabuk.
