Abu Musa reported that Allah's Messenger ﷺ said, “The guidance and knowledge with which Allah has commissioned me are like abundant rain which fell on some ground. Part of it was good, and absorbing the water, it brought forth abundant herbage and pasture; and there were some bare patches in it which retained the water by which Allah gave benefit to men, who drank, gave drink and sowed seed. But some of it fell on another portion which consisted only of hollows which could not retain the water or produce herbage. That is like the one who becomes versed in Allah’s religion and receives benefit from the message entrusted to me by Allah, so he knows for himself and teaches others ; and it is like the one who does not show regard to that and does not accept Allah’s guidance with which I have been commissioned.” (Bukhari and Muslim.)

‘A'isha told that when Allah's Messenger ﷺ saw rain he said, “O Allah, send a beneficial downpour." Bukhari transmitted it.

Anas said

‘Abdallah b. Zaid said Allah's Messenger ﷺ went out to the place of prayer and prayed for rain. When he faced the qibla he turned round his cloak, putting its right side on his left shoulder and its left side on his right shoulder, then made supplication to Allah. Abu Dawud transmitted it.

He said Allah's Messenger ﷺ prayed for rain wearing a khamisa* of his. He wanted to reverse it from top to bottom, but when it was too heavy he turned it round on his shoulders. * A black square robe with ornamented borders. Ahmad and Abu Dawud transmitted it.

‘Umair client of Abul Lahm said he saw the Prophet (ﷺ) praying for rain at Ahjar az-Zait1 near az-Zaura’,2 standing, making supplication, praying for rain and raising his hands in front of his face, but not lifting them above his head. 1. A part of Medina which is said to have got the name because of the black stones there which looked as if they had been smeared with oil. 2. A house in Medina. Abu Dawud transmitted it, and Tirmidhi and Nasa’i transmitted something similar.

Ibn 'Abbas said Allah's Messenger ﷺ went out (i.e. to pray for rain) wearing old clothes, with a humble and lowly manner, making petition. Tirmidhi, Abu Dawud, Nasa’i and Ibn Majah transmitted it.

'Amr b. Shu'aib, on his father’s authority, quoted his grandfather as saying that when the Prophet (ﷺ) prayed for rain he said, "O Allah, provide water for Thy servants and Thy cattle, display Thy mercy and give life to Thy dead land.” Malik and Abu Dawud transmitted it.

Jabir said he saw Allah's Messenger ﷺ raising his hands in supplication. Then he said, “O Allah, give us rain which will replenish us, abundant, fertilising and profitable, not injurious, granting it now without delay.” He said that thereupon the sky became overcast. Abu Dawud transmitted it.

'A’isha said the people complained to Allah's Messenger ﷺ of the lack of rain, so he gave orders for a pulpit, and when it was set up for him in the place of prayer he appointed a day for the people on which they should come out. ‘A’isha said Allah's Messenger ﷺ came out when the rim of the sun appeared and sat down on the pulpit. Having declared Allah’s greatness and expressed His praise, he said, “You have complained of drought in your abodes and of delay in receiving rain at the beginning of its season, but Allah has ordered you to supplicate Him and has promised that He would answer your prayers.” Then he said, “Praise be to Allah, the Lord of the universe, the Compassionate, the Merciful, the Master of the day of judgment. There is no Allah but Allah who does what He wishes. O Allah, Thou art Allah than whom there is no god, the Rich, while we are the poor. Send down rain upon us and make what Thou sendest down a strength and satisfaction for us for a time.” He then raised his hands and kept raising them till the whiteness under his armpits was visible. He then turned his back to the people and inverted (or, turned round) his cloak while keeping his hands aloft. He then faced the people, descended and prayed two rak'as. Allah then produced a cloud and a storm of thunder and lightning came on. Then it rained by Allah’s permission, and before he reached his mosque streams were flowing. When he saw the speed with which the people sought shelter he laughed till his back teeth were visible. Then he said, “I testify that Allah is omnipotent and that I am Allah’s servant and Messenger.” Abu Dawud transmitted it.

Anas said that when they experienced a drought ‘Umar b. al-Khattab prayed for rain by virtue of al-‘Abbas b. ‘Abd al-Muttalib, and said, "O Allah, we used to supplicate Thee by virtue of our prophet and Thou didst give us water. We are now supplicating Thee by virtue of our prophet’s uncle, so give us water.” He said that they were then given water. Bukhari transmitted it.
