Al-Matalib al-'Aliyah 960 — Encouragement to give charity

It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him) that a man from the tribe of Banu Tamim came into the presence of the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah, I have a great deal of wealth and property, I also have a family, and I am a man of wealth and standing; so tell me how I should spend my wealth and what course of action I should adopt (for good)? The Messenger of Allah (peace and blessings be upon him) said: "Pay the zakah on your wealth, for it is a purification that will purify you (from sins and from the impurity of wealth); treat your relatives kindly and uphold the ties of kinship; and recognise the right of the one who asks, the neighbour and the poor." He (peace and blessings be upon him) also referred to this blessed verse: "And give the relative his right, and the poor and the wayfarer" [Surah al-Isra: 26].
Imam al-Harith bin Abi Usamah (may Allah have mercy on him) narrated this hadith, which sets out a comprehensive Qur'anic and Prophetic economic order comprising the purification of the self through zakah and the fulfilment of the financial rights of relatives and the poor.
