Abu Hurairah narrated that the Messenger of Allah (ﷺ) said: “There is not a man who calls upon Allah with a supplication, except that he is answered. Either it shall be granted to him in the world, or reserved for him in the Hereafter, or, his sins shall be expiated for it according to the extent that he supplicated - as long as he does not supplicate for some sin, or for the severing of the ties of kinship, and he does not become hasty.” They said: “O Messenger of Allah, and how would he be hasty?” He (ﷺ) said: “He says: ‘I called upon my Lord, but He did not answer me.’”
