Abu Sa'id al-Khudri said some of the Ansar begged from Allah's Messenger ﷺ and he gave them something. They later begged from him again and he gave them something so that what he had was exhausted. He then said, “What I have I shall never store away from you, but Allah will strengthen the abstinence of him who abstains, will give a competence to him who is satisfied, and will strengthen the endurance of him who shows endurance. No one has been given a better or more ample gift than endurance.” (Bukhari and Muslim.)
