Mussanaf Ibn Abi Shaybah (Vol.6)

Malik al-Dar i.e. treasurer of Umar (RA) relates: The people were gripped by drought during the tenure of Umar (Ibn-ul-Khattab). Then a man “WALKED UP TO THE GRAVE OF PROPHET AND SAID: O MESSENGER OF ALLAH! ASK FOR RAIN” for your Ummah who is in dire straits. Then he saw the Prophet (SAW) in dream. The Prophet (SAW) said to him, Go over to Umar, give him my regards and tell him that the rain will come to you. And tell Umar that he should be on his toes, he should be on his toes (he should remain alert). He went over to see Umar and passed on to him the tidings. On hearing this, Umar broke into a spurt of crying. He said, O Allah, I exert myself to the full until I am completely exhausted. [Musannaf Ibn Abi Shaybah, Hadith # 31993]..
