Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates that a man from Banu Tamim came to the Messenger of Allah (peace and blessings be upon him) and asked: O Messenger of Allah! If I pay zakat to your appointed representative, will I be absolved before Allah and His Messenger? The Messenger of Allah (peace and blessings be upon him) said: Yes, when you pay zakat to my representative, your responsibility will be fulfilled and you will receive its reward. However, whoever makes any alteration (and misappropriates it), he will be sinful.
