If I'm not mistaken this is a supplication for rain made by the Prophet, peace and blessings be upon him.
Asbath added on the authority of Mansur, "Allah's Apostle prayed for them and it rained heavily for seven days. So the people complained of the excessive rain. The Prophet said, 'O Allah! (Let it rain) around us and not on us.' So the clouds dispersed over his head and it rained over the surroundings."
