The Prophet ﷺ said (in the meaning), “Whenever a Muslim supplicates Allah, He grants his supplication or avert a harm from him of equal proportions, as long as he does not supplicate for something sinful or something that would cut off the ties of kinship.” Thereupon someone said: Then we shall supplicate plenty. The Prophet ﷺ said: Allah is more plentiful in responding.” [at-Tirmidhi, Al–Hakim’s version adds: “…Or lays up an equivalent reward for him.”].
