Sayyiduna Abu Musa Ash'ari (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When a servant's child dies, Allah, the Exalted, asks the angels: 'Did you take the soul of My servant's child?' They reply: 'Yes.' Allah then asks: 'Did you take the fruit of his heart?' They reply: 'Yes.' So Allah says: 'What did My servant say?' They inform Him that he praised You and recited «انا لله وانا اليه راجعون» . Then Allah says: 'Build a house for My servant in Paradise and name it "Bayt al-Hamd" (the House of Praise).'"
