Silsilat al-Ahadith al-Sahihah

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."
