Sahih al-Bukhari 4255Book 64, Hadith 289
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.
