Musnad Ahmad

It is narrated from Hazrat Sahl bin Hanzalah (may Allah be pleased with him) that once the Prophet (peace and blessings be upon him), Uyainah and Aqra’ asked for something. The Prophet (peace and blessings be upon him) ordered Hazrat Amir Muawiyah (may Allah be pleased with him) to write it for them. He wrote it. The Prophet (peace and blessings be upon him) sealed it and ordered that the letter be handed over to them. Uyainah asked, "What is written in it?" He replied, "What you had wished for." Uyainah kissed it and wrapped it in his turban. Uyainah was more intelligent than both of them, while Aqra’ said, "Should I go around carrying a document like a beggar, about which I do not know what is written in it?" Hazrat Muawiyah (may Allah be pleased with him) informed the Prophet (peace and blessings be upon him) about what both of them had said. The Prophet (peace and blessings be upon him) went out for some work and in the early part of the day passed by a camel tied at the door of the mosque. When he passed by there in the latter part of the day, the camel was still tied in the same way. The Prophet (peace and blessings be upon him) asked, "Where is the owner of this camel?" Despite searching, its owner was not found. The Prophet (peace and blessings be upon him) said, "Fear Allah regarding these animals. Ride them when they are healthy and strong." Then he said, "Whoever asks while he has enough to fulfill his need, as just now someone who showed displeasure did, then he is adding to the coals of Hell." The companions (may Allah be pleased with them) asked, "O Messenger of Allah (peace and blessings be upon him), what is meant by need?" He replied, "Food."
