Sunan an-Nasa'i 1521

Mahmud ibn Ghaylan narrated to us; he said: Waki‘ narrated to us; he said: Sufyan narrated to us, from Hisham ibn Ishaq ibn ‘Abdullah ibn Kinanah, from his father, who said: One of the governors sent me to Ibn ‘Abbas to ask him about the prayer for rain. Ibn ‘Abbas said, “What prevented him from asking me? The Messenger of Allah (peace and blessings be upon him) went out humbly, simply dressed, submissive, and imploring. He prayed two rak‘ahs as he would pray on the two Eids, and did not deliver a sermon like this sermon of yours.”
