“When Mughirah bin Shu’bah fought alongside the Prophet ﷺ he would carry a spear, and when he would come back he would throw his spear down so that someone would pick it up and give it back to him.” ‘Ali said to him: “I will tell the Messenger of Allah ﷺ about that.” He (the Prophet ﷺ) said: “Do not do that, for it you do that it will not be picked up as a lost item to be returned.”
كَانَ الْمُغِيرَةُ بْنُ شُعْبَةَ إِذَا غَزَا مَعَ النَّبِيِّ ﷺ حَمَلَ مَعَهُ رُمْحًا فَإِذَا رَجَعَ طَرَحَ رُمْحَهُ حَتَّى يُحْمَلَ لَهُ فَقَالَ لَهُ عَلِيٌّ لأَذْكُرَنَّ ذَلِكَ لِرَسُولِ اللَّهِ ﷺ فَقَالَ لاَ تَفْعَلْ فَإِنَّكَ إِنْ فَعَلْتَ لَمْ تُرْفَعْ ضَالَّةٌ
