Sayyiduna Muhammad bin Abi Umairah, may Allah be pleased with him, who was a companion of the Messenger, narrates that he said: If a person, from the day of his birth until he grows old and dies, spends his entire life in obedience to Allah Almighty, prostrating on his face, even then on the Day of Resurrection he will consider this obedience as insignificant and will wish that he be sent back to the world so that he may perform more good deeds and attain greater reward and recompense.
