Sayyiduna Abu Umamah (may Allah be pleased with him) said: A man from the Ansar came to the Messenger of Allah (peace and blessings be upon him), while Sayyiduna Abu Bakr and Sayyiduna Umar (may Allah be pleased with them both) were with him (peace and blessings be upon him), and he said: So-and-so sowed a crop and its yield doubled, or words to that effect. So the Messenger of Allah (peace and blessings be upon him) said: "What is that? Two light rak'ahs are better for you than all of that, than the world and all that is on it. And if you did what you have been commanded, you would eat without tilling crops and without toiling."
