اللَّهُمَّ صَيِّبًا نَافِعًا
Allahumma sayyiban nafi'a
O Allah, let it be a beneficial rain.
The Prophet ﷺ would say this when he saw rain. Rain is a time when du'as are answered — the Prophet ﷺ said: "Two du'as are not rejected: the du'a at the time of the adhan, and the du'a at the time of rain."
