Anbasah bin Abi Sufyan (may Allah have mercy on him) narrates from his sister Umm Habibah (may Allah be pleased with her) that the Prophet (peace and blessings be upon him) said: "For the one who offers twelve rak'ahs of prayer in a day, Allah Almighty will build a house in Paradise: four before Zuhr and two after it, two before Asr, two after Maghrib and two before Fajr."
