Translations:On Dokuzuncu Mektup/532/en
The fact that prayers of the Noble Messenger (Upon whom be blessings and peace) for rain were always accepted has been transmitted by authorities of Hadith, primarily Bukhari and Muslim. There were times when in the pulpit he raised his hands to pray for rain, and before he had lowered them even, rain began to fall.(*[1])As mentioned above, once or twice when the army had run out of water, the clouds came and poured forth rain.(*[2])
