Some of the Ansar begged from the Messenger of Allah (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 satisfaction to him who wants to be satisfied, and will strengthen the endurance of him who shows endurance. No one has been given a more ample gift than endurance.
