Mukhtasar Muslim

It is narrated from Sayyiduna Abu Sa'id Khudri (may Allah be pleased with him) that some people from the Ansar asked the Messenger of Allah (peace and blessings be upon him) for something, so he gave them. They asked again, and he gave them again, until whatever he had was finished. Then the Messenger of Allah (peace and blessings be upon him) said: "Whatever wealth I have, I do not withhold it from you. And whoever refrains from asking, Allah will protect him; and whoever makes himself self-sufficient, Allah will make him self-sufficient; and whoever strives to be patient, Allah will grant him patience. And no gift from Allah is better and more expansive than patience."
