It is narrated from Sayyiduna Abu Umamah (may Allah be pleased with him) that at the end of his meal the Prophet (peace and blessings be upon him) would say: "All praise is for Allah, abundant praise, pure and blessed, from which we are not made free of need, nor is it abandoned, and nor, O our Lord, are we free of need of You."
