CHAPTER: On Collecting Charity.
Narrated Rafi ibn Khadij: I heard the Messenger of Allah صلی اللہ علیہ وسلم say: The official who collects sadaqah (zakat) in a just manner is like him who fights in Allah's path till he returns home.
Narrated Uqbah ibn Amir: I heard the Messenger of Allah صلی اللہ علیہ وسلم as saying: One who wrongfully takes an extra tax (sahib maks) will not enter Paradise.
Narrated Ibn Ishaq: Sahib maks means one who (receives) tithes (from) people.
