(35) باب النَّهْىِ عَنِ الإِشَارَةِ، بِالسِّلاَحِ إِلَى مُسْلِمٍ
Abu Huraira reported a hadith from Allah's Messenger (ﷺ) ; (one of them was this) that Allah's Messenger (ﷺ) said:
None amongst you should point a weapon towards his brother, for he does not know that Satan might cause the weapon (to slip) from his hand and (he may injure anyone) and thus he may fall into Hell-Fire.
