Sahih al-Bukhari · Book 64: Military Expeditions led by the Prophet (pbuh) (Al-Maghaazi) · ‘'Umra Al-Qada’
Narrated Ibn Abi `Aufa:
حَدَّثَنَا عَلِيُّ بْنُ عَبْدِ اللَّهِ ، حَدَّثَنَا سُفْيَانُ ، عَنْ إِسْمَاعِيلَ بْنِ أَبِي خَالِدٍ ، سَمِعَ ابْنَ أَبِي أَوْفَى ، يَقُولُ لَمَّا اعْتَمَرَ رَسُولُ اللَّهِ صلى الله عليه وسلم سَتَرْنَاهُ مِنْ غِلْمَانِ الْمُشْرِكِينَ وَمِنْهُمْ، أَنْ يُؤْذُوا رَسُولَ اللَّهِ صلى الله عليه وسلم.
When Allah's Messenger (ﷺ) performed the `Umra (which he performed in the year following the treaty of Al-Hudaibiya) we were screening Allah's Messenger (ﷺ) from the infidels and their boys lest they should harm him.
