It was narrated that Abu Musa said: “The Messenger of Allah صلی اللہ علیہ وآلہ وسلم said: ‘The believers are like a building, they support one another.’ And he said: ‘The trustworthy storekeeper who gives that which he has been commanded to give, and is happy with what he is doing, is one of the two giving charity.” (Sahih)
