It was narrated from Hisham binIshaq bin Abdullah bin Kinanah that:
His father said: I asked Ibn 'Abbas how the Messenger of Allah (ﷺ) prayed for rain. He said: 'The Messenger of Allah (ﷺ) went out (dressed) in a state of humility, beseeching and humble. He sat on the minbar but he did not deliver a Khutbah like this Khutbah of yours, rather he kept supplicating, beseeching and saying the takbir, and he prayed two rak'ahs as he used to do during the two 'Eids.'
