One-fifth of Booty to the Cause of Allah (Khumus)
57/7. Chapter:
The Statement of Allah تعالى: "Verily one-fifth (1/5th) of it is assigned to Allah and to the Messenger ﷺ ..." (V.8:41)
يَعْنِي لِلرَّسُولِ قَسْمَ ذَلِكَ. قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: «إِنَّمَا أَنَا قَاسِمٌ وَخَازِنٌ، وَاللَّهُ يُعْطِي».It means that Allah's Messenger ﷺ had the authority of distributing it (i.e., the fifth share), for Allah's Messenger ﷺ said, "I am a distributor and a treasurer, and Allah is the Giver."
Sahih Bukhari
حَدَّثَنَا مُحَمَّدُ بْنُ سِنَانٍ، حَدَّثَنَا فُلَيْحٌ، حَدَّثَنَا هِلاَلٌ، عَنْ عَبْدِ الرَّحْمَنِ بْنِ أَبِي عَمْرَةَ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " مَا أُعْطِيكُمْ وَلاَ أَمْنَعُكُمْ، أَنَا قَاسِمٌ أَضَعُ حَيْثُ أُمِرْتُ ".
Abu Huraira: Allah's Messenger (ﷺ) said, "Neither do I give you (anything) nor withhold (anything) from you, but I am just a distributor (i.e. Qasim), and I give as I am ordered."
