Sunan Ibn Majah 1266

It was narrated from Hisham bin Ishaq bin ‘Abdullah bin Kinanah that his father said:“One of the chiefs* sent me to Ibn ‘Abbas to ask him about the prayer for rain. Ibn ‘Abbas said: ‘What kept him from asking me?’ He said: ‘The Messenger of Allah (ﷺ) went out humbly, walking with a humble and moderate gait, imploring, and he performed two Rak’ah as he used to pray for ‘Eid, but he did not give a sermon like this sermon of yours.’”
