THE SMART TRICK OF RAJASBO THAT NOBODY IS DISCUSSING

In the event the thirty day period of Rajab arrived, we'd say Munassil al-Asinnah [the one particular that causes the sharp heads of weapons to be taken off], and we wouldn't depart any spear or arrow that had an iron piece in it but we'd go ahead and take metal head off and set it apart in the thirty day period of Rajab. (Narrated by al-Bukhari)
