Silsilat al-Ahadith al-Sahihah

It is narrated from Sayyiduna Hani (may Allah be pleased with him), he says: When I came to the Messenger of Allah (peace and blessings of Allah be upon him) as part of a delegation, I asked: O Messenger of Allah! Which deed makes Paradise obligatory? The Prophet (peace and blessings of Allah be upon him) said: “Adhere to speaking good words and feeding others.”
