“And when My slaves ask you concerning Me, then (answer them), I am indeed near. I respond to the invocations of the supplicant when he calls on Me. So let them obey Me and believe in Me, so that they may be led aright.” (Qur’an, Al-Baqarah: 186)
Abu Hurairah – may Allaah be pleased with him – reported: The Messenger of Allaah – peace and blessings of Allaah be upon him – said: “The supplication of every one of you will be granted if he does not get impatient and say (for example): `I supplicated my Rubb (Lord) but my prayer has not been granted‘.” [Al-Bukhari and Muslim].
Abu Hurairah – may Allaah be pleased with him – reported: The Messenger of Allaah – peace and blessings of Allaah be upon him – said, “A slave becomes nearest to his Rubb (Lord) when he is in prostration. So increase supplications in prostrations.” [Muslim].
“If a person recites a du’aa’ that is mentioned in the Qur’aan when prostrating, such as the words (interpretation of the meaning): “Our Lord! Give us in this world that which is good and in the Hereafter that which is good, and save us from the torment of the Fire” [al-Baqarah 2:201], there is nothing wrong with that, if the intention is to say du’aa’ and not to recite Qur’aan, because the Prophet (peace and blessings of Allaah be upon him) said: “Actions are but by intentions, and each person will have but that which he intended.” Narrated by al-Bukhaari, 1; Muslim, 1907.”
