Abu Sa'id reported God’s Messenger as saying, “When one of you beats his servant and he makes mention of God, you must stop beating him.” Tirmidhi and Baihaqi, in <i>Shu'ab al-iman</i>, transmitted it, but the latter has, “he should stop” instead of “you must stop beating him.”

وَعَنْ أَبِي سَعِيدٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِذَا ضَرَبَ أَحَدُكُمْ خَادِمَهُ فَذَكَرَ اللَّهَ فَارْفَعُوا أَيْدِيَكُمْ» . رَوَاهُ التِّرْمِذِيُّ وَالْبَيْهَقِيُّ فِي شُعَبِ الْإِيمَانِ لَكِنْ عِنْدَهُ «فَلْيُمْسِكْ» بدل «فارفعوا أَيْدِيكُم»
