It was
narrated that ‘Ali bin Abi Talib said:
“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.”
