Sahih Bukhari

The Prophet (ﷺ) went out to offer the Istisqa' prayer and turned (and put on) his cloak inside out.

Whenever the Prophet (ﷺ) lifted his head from the bowing in the last rak`a he used to say: "O Allah! Save `Aiyash bin Abi Rabi`a. O Allah! Save Salama bin Hisham. O Allah! Save Walid bin Walid. O Allah! Save the weak faithful believers. O Allah! Be hard on the tribes of Mudar and send (famine) years on them like the famine years of (Prophet) Joseph ." The Prophet (ﷺ) further said, "Allah forgive the tribes of Ghifar and save the tribes of Aslam." Abu Az-Zinad (a sub-narrator) said, "The Qunut used to be recited by the Prophet (ﷺ) in the Fajr prayer."

We were with `Abdullah and he said, "When the Prophet (ﷺ) saw the refusal of the people to accept Islam he said, "O Allah! Send (famine) years on them for (seven years) like the seven years (of famine during the time) of (Prophet) Joseph." So famine overtook them for one year and destroyed every kind of life to such an extent that the people started eating hides, carcasses and rotten dead animals. Whenever one of them looked towards the sky, he would (imagine himself to) see smoke because of hunger. So Abu Sufyan went to the Prophet (ﷺ) and said, "O Muhammad! You order people to obey Allah and to keep good relations with kith and kin. No doubt the people of your tribe are dying, so please pray to Allah for them." So Allah revealed: "Then watch you For the day that The sky will bring forth a kind Of smoke Plainly visible ... Verily! You will return (to disbelief) On the day when We shall seize You with a mighty grasp. (44:10-16) Ibn Mas`ud added, "Al-Batsha (i.e. grasp) happened in the battle of Badr and no doubt smoke, Al-Batsha, Al-Lizam, and the verse of Surat Ar-Rum have all passed .

My father said, "I heard Ibn `Umar reciting the poetic verses of Abu Talib: And a white (person) (i.e. the Prophet) who is requested to pray for rain and who takes care of the orphans and is the guardian of widows." Salim's father (Ibn `Umar) said, "The following poetic verse occurred to my mind while I was looking at the face of the Prophet (ﷺ) while he was praying for rain. He did not get down till the rain water flowed profusely from every roof-gutter: And a white (person) who is requested to pray for rain and who takes care of the orphans and is the guardian of widows . . . And these were the words of Abu Talib."

Whenever drought threatened them, `Umar bin Al-Khattab, used to ask Al-Abbas bin `Abdul 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.

The Prophet (ﷺ) turned his cloak inside out on Istisqa.

The Prophet (ﷺ) went towards the Musalla and invoked Allah for rain. He faced the Qibla and wore his cloak inside out, and offered two rak`at.
