´Abu Hurairah [may Allah be pleased with him] narrated :` that the Messenger of Allah said: “Three supplications are responded to: The supplication of the oppressed, the supplication of the traveler, and the supplication of the parent against his child.” Ali bin Hujr narrated to us (he said): Ismail bin Ibrahim reported to us from Hisham Ad-Dastawa’i, from Yahya bin Abu Kathir with this chain, narrating similar to it, but he added to it: “responded to, there is no doubt in them.”
