Safwan (and he was Ibn 'Abdullah b. Safwan, and he had been married to Umm Darda') reported: I visited Abu Darda's house in Syria. I did not find him there but Umm Darda' (was present at the house). She said: Do you intend to perform Hajj during this year? I said: Yes. She said: Do supplicate Allah for blessings upon us, for Allah's Apostle (may peace be upon hiin) used to say: The supplication of a Muslim for his brother at his back (in his absence) is responded so long as he makes a supplica- tion for blessings for his brother and the commissioned Angel says: Amen, and says: May it be for you too I I went to the bazar and met Abfi Dardi' and he narrated like this from Allah's Messenger (ﷺ).
Anas b. Malik reported that Allah's Messenger (ﷺ) said: Allah is pleased with His servant who says: Al-Hamdu lillah while taking a morsel of food and while drinking.
Abu Huraira reported that Allah's Messenger (ﷺ) said: The supplication of every one of you is granted if he does not grow impatient and says: I supplicated but it was not granted.
Abu Huraira reported Allah's Messenger (ﷺ) as saying: The supplication of one of you is granted if he does not grow impatient and say- I supplicated my Lord but it was not granted.
Abu Huraira reported Allah's Messenger (ﷺ) as saying: The supplication of the servant is granted in case he does not supplicate for sin or for severing the ties of blood, or he does not become impatient. It was said: Allah's Messenger, what does:" If he does not grow impatient" imply? He said: That he should say like this: I supplicated and I supplicated but I did not find it being responded. and theu he becomes frustrated and abandons supplication.
