نَفَّلَنَا رَسُولُ اللَّهِ صلى الله عليه وسلم نَفَلاً سِوَى نَصِيبِنَا مِنَ الْخُمْسِ فَأَصَابَنِي شَارِفٌ وَالشَّارِفُ الْمُسِنُّ الْكَبِيرُ
A hadith has been narrated by Salim who learnt it from his father and said:The Messenger of Allah (ﷺ) gave us an extra (camel) besides our share of Khums; (and in this extra share) I got a Sharif (and a Sharif is a big old camel)
It has been narrated on the authority of Abdullah b. 'Umar that the Messenger of Allah (ﷺ) used to give (from the spoils of war) to small troops seat on expeditions something more than the due share of each fighter in a large force. And Khums (one-fifth of the total spoils) was to be reserved (for Allah and His Apostle) in all cases
