Narrated Anas bin Malik

A man came to Allah's Apostle and said, "O Allah's Apostle! Livestock are destroyed and the roads are cut off; so please invoke Allah." So Allah's Apostle prayed for rain and it rained from that Friday till the next Friday. Then a man came to the Prophet (p.b.u.h) and said, "O Allah's Apostle! The houses have collapsed, roads are cut off and the livestock are destroyed." So Allah's Apostle said, "O Allah ! (Let it rain) on the tops of the mountains, on the plateaus, in the valleys and over the places where trees grow." So the clouds cleared away from Medina as clothes are taken off.

Bukhari :: Book 2 :: Volume 17 :: Hadith 133

Narrated Masruq:

One day I went to Ibn Masud who said, "When Quraish delayed in embracing Islam, the Prophet I invoked Allah to curse them, so they were afflicted with a (famine) year because of which many of them died and they ate the carcasses and Abu Sufyan came to the Prophet and said, 'O Muhammad! You came to order people to keep good relation with kith and kin and your nation is being destroyed, so invoke Allah I ? So the Prophet I recited the Holy verses of Sirat-Ad-Dukhan: 'Then watch you For the day that The sky will Bring forth a kind Of smoke Plainly visible.' (44.10) When the famine was taken off, the people renegade once again as nonbelievers. The statement of Allah, (in Sura "Ad-Dukhan"-44) refers to that: 'On the day when We shall seize You with a mighty grasp.' (44.16) And that was what happened on the day of the battle of Badr." Asbath added on the authority of Mansur, "Allah's Apostle prayed for them and it rained heavily for seven days. So the people complained of the excessive rain. The Prophet said, 'O Allah! (Let it rain) around us and not on us.' So the clouds dispersed over his head and it rained over the surroundings."
