Sayyiduna Abu Usayd al-Sa'idi (may Allah be pleased with him) said: I was the youngest of the Companions of the Messenger of Allah (peace and blessings be upon him) and the one who heard the most from him (peace and blessings be upon him). The Messenger of Allah (peace and blessings be upon him) said: "Nothing remains for a child of kindness towards his father except four kinds of kindness: 1. Offering the funeral prayer for him. 2. Praying for him. 3. Carrying out his bequest after him and maintaining ties of kinship. 4. Honouring his friends."
