BUKHARI 1010:
from ʿUmar —
Whenever drought threatened them, ʿUmar bin Al-Khattab, used to ask Al-Abbas bin ʿAbdul Muttalib to invoke Allah for rain. He used to say, "O Allah! We used to ask our Prophet to invoke You for rain, and You would bless us with rain, and now we ask his uncle to invoke You for rain. O Allah ! Bless us with rain."(1) And so it would rain.

عن عمر —
أَنَّ عُمَرَ بْنَ الْخَطَّابِ ؓ كَانَ إِذَا قَحَطُوا اسْتَسْقَى بِالْعَبَّاسِ بْنِ عَبْدِ الْمُطَّلِبِ فَقَالَ اللَّهُمَّ إِنَّا كُنَّا نَتَوَسَّلُ إِلَيْكَ بِنَبِيِّنَا فَتَسْقِينَا وَإِنَّا نَتَوَسَّلُ إِلَيْكَ بِعَمِّ نَبِيِّنَا فَاسْقِنَا قَالَ فَيُسْقَوْنَ
