Uyayna bin Hisn and Aqra bin Habis came to the Messenger of Allah ﷺ and asked him for something. He ordered that they be given what they had requested, and he instructed Muawiya to write out the grants for them.Aqra took his document, folded it into his turban, and went on his way. As for Uyayna, he took his document and came back to the Prophet ﷺ at the same spot and said, "Muhammad, do you see me carrying back to my people a document whose contents I do not know, like the letter of Mutalammis?"Muawiya informed the Messenger of Allah ﷺ of what Uyayna had said.The Messenger of Allah ﷺ said, "Whoever asks for something while having enough to suffice him is only seeking to increase his share of the Fire." Nufayli, in another place, said, "of the embers of Hell."They asked, "Messenger of Allah, what amount counts as sufficiency?" Nufayli, in another place, said, "What is the level of sufficiency that makes asking improper?"He replied, "The amount that provides his lunch and his dinner." Nufayli, in another place, said, "That he has enough to satisfy him for a day and a night, or a night and a day."He narrated it to us in this abridged form, with the wording I have mentioned.
حدثنا عبد الله بن محمد النفيلي حدثنا مسكين حدثنا محمد بن المهاجر عن ربيعة بن يزيد عن أبي كبشة السلولي
قدم على رسول الله ﷺ عيينة بن حصن والأقرع بن حابس فسألاه فأمر لهما بما سألا وأمر معاوية فكتب لهما بما سألا فأما الأقرع فأخذ كتابه فلفه في عمامته وانطلق وأما عيينة فأخذ كتابه وأتى النبي ﷺ مكانه فقال يا محمد أتراني حاملا إلى قومي كتابا لا أدري ما فيه كصحيفة المتلمس فأخبر معاوية بقوله رسول الله ﷺ فقال رسول الله ﷺ من سأل وعنده ما يغنيه فإنما يستكثر من النار وقال النفيلي في موضع آخر من جمر جهنم فقالوا يا رسول الله وما يغنيه وقال النفيلي في موضع آخر وما الغنى الذي لا تنبغي معه المسألة قال قدر ما يغديه ويعشيه وقال النفيلي في موضع آخر أن يكون له شبع يوم وليلة أو ليلة ويوم وكان حدثنا به مختصرا على هذه الألفاظ التي ذكرت
