question #3 Sahih Muslim 1053a, Book 12, Hadith 161 : What is considered the greatest endowment a person can receive in Islam?

Whatever good (riches, goods) I have, I will not withhold it from you. He who refrains from begging Allah safeguards him against want. and he who seeks sufficiency, Allah would keep him in a state of sufficiency, and he who shows endurance. Allah would grant him power to endure, and none is blessed with an endowment better and greater than endurance.
