Silsilah as-Sahihah 2099 — Treating delegations well

It is narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) that the Messenger of Allah (peace and blessings be upon him) made three bequests: "Expel the polytheists from the Arabian Peninsula, treat the delegations as I do." Ibn Abbas (may Allah be pleased with them both) said: Regarding the third thing, he (the Prophet) remained silent, or he said: "I have been made to forget it."
