Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: "The supplication of three persons is not rejected: the supplication of a fasting person until he breaks his fast, the supplication of a just ruler or king, and the supplication of an oppressed person. Allah, the Exalted, raises his supplication above the clouds and opens the gates of the heavens for it. Then the Lord, Mighty and Majestic, says: 'By My honor, I will surely help you, even if after some time.'" Abu Mujahid's name is Sa'd Tai, and Abu Mudlah was the freed slave of Sayyiduna Abu Hurairah (may Allah be pleased with him). And Amr bin Qais was among the worshippers of the world.
