Sahih al-Bukhari 3507

خَرَجَ رَسُولُ اللَّهِ صلى الله عليه وسلم عَلَى قَوْمٍ مِنْ أَسْلَمَ، يَتَنَاضَلُونَ بِالسُّوقِ، فَقَالَ ‏"‏ ارْمُوا بَنِي إِسْمَاعِيلَ، فَإِنَّ أَبَاكُمْ كَانَ رَامِيًا، وَأَنَا مَعَ بَنِي فُلاَنٍ ‏"‏‏.‏ لأَحَدِ الْفَرِيقَيْنِ، فَأَمْسَكُوا بِأَيْدِيهِمْ فَقَالَ ‏"‏ مَا لَهُمْ ‏"‏‏.‏ قَالُوا وَكَيْفَ نَرْمِي وَأَنْتَ مَعَ بَنِي فُلاَنٍ‏.‏ قَالَ ‏"‏ ارْمُوا وَأَنَا مَعَكُمْ كُلِّكُمْ ‏"‏‏.

“Allah's Messenger ﷺ passed by some people from the tribe of Aslam practicing archery. He said, "O children of Ishmael! Throw (arrows), for your father was an archer. I am on the side of Bani so-and-so," meaning one of the two teams. The other team stopped throwing, whereupon the Prophet ﷺ said, "What has happened to them?" They replied, "How shall we throw while you are with Bani so-and-so?" He said, "Throw for I am with all of you”
