Mukhtasar Bukhari (Abridged) 12 — Feeding others is part of Islam

Narrated from Sayyiduna Abdullah bin Amr (may Allah be pleased with them both) that a man asked the Messenger of Allah (peace and blessings of Allah be upon him): "Which Islam is best?" He (peace and blessings of Allah be upon him) replied: "Feed (others) and greet with Salam those whom you know and those whom you do not know (all of them)."
