Safwan (and he was Ibn Abdullah bin Safwan, and he had been married to Umm Darda) reported: I visited Abu Dardas 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 Allahs Apostle ﷺ (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 supplication for blessings for his brother and the commissioned Angel says: Amen, and says: May it be for you too. I went to the bazar and met Abfi Dardi and he narrated like this from Allahs Messenger ﷺ .
