سورة البقرة , Al-Baqara, Chapter #2
, Verse #286
The Prophet(saw) said: “Your supplication will be answered if you are not impatient, and if you do not say, ‘I supplicated but my supplication was not heard.’” (Malik)
The Prophet (peace and blessings of Allah be upon him) said: “The slave will receive a response so long as his dua does not involve sin or severing of family ties, and so long as he is not hasty.” It was said, “What does being hasty mean?”
He said: “When he says, ‘I made dua and I made dua, and I have not seen any response,’ and he gets frustrated and stops making dua.” Narrated by al-Bukahari, 6340; Muslim, 2735.
