Jabir b. Abdullah reported that a person happened to come to the mosque with arrows and their iron-ends were exposed, so he was commanded that he should grasp the pointed heads so that these might not do any harm to a Muslim.

أَنَّ رَجُلاً مَرَّ بِأَسْهُمٍ فِي الْمَسْجِدِ قَدْ أَبْدَى نُصُولَهَا فَأُمِرَ أَنْ يَأْخُذَ بِنُصُولِهَا كَىْ لاَ يَخْدِشَ مُسْلِمًا
