مَّنْ عَمِلَ صَٰلِحًۭا فَلِنَفْسِهِۦ ۖ وَمَنْ أَسَآءَ فَعَلَيْهَا ۗ وَمَا رَبُّكَ بِظَلَّٰمٍۢ لِّلْعَبِيدِ
Whoso doeth right it is for his soul, and whoso doeth wrong it is against it. And thy Lord is not at all a tyrant to His slaves.
Surah Fussilat(41:46)
Sahih al-Bukhari
One-fifth of Booty to the Cause of Allah (Khumus)
Chapter: What the Prophet saws used to give to those Muslims whose faith was not so firm
Narrated `Abdullah:
On the day (of the battle) of Hunain, Allah's Messenger (ﷺ) favored some people in the distribution of the booty (to the exclusion of others); he gave Al-Aqra' bin H`Abis one-hundred camels and he gave 'Uyaina the same amount, and also gave to some of the eminent Arabs, giving them preference in this regard. Then a person came and said, "By Allah, in this distribution justice has not been observed, nor has Allah's Pleasure been aimed at." I said (to him), "By Allah, I will inform the Prophet (of what you have said), "I went and informed him, and he said, "If Allah and His Apostle did not act justly, who else would act justly. May Allah be merciful to Moses, for he was harmed with more than this, yet he kept patient."
