Musannaf Ibn Abi Shaybah 27401 — Reports on spreading the greeting

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "By the One in whose Hand is my soul, you will not enter Paradise until you believe, and you will not believe until you love one another. Shall I not guide you to a matter which, when you do it, you will love one another? Make the greeting of peace (salam) widespread."
