Behold! you are those who are called upon to spend in the cause of Allâh. Yet some of you are niggardly. (Remember that) whoever is niggardly is niggardly only against his own self. Otherwise Allâh is Self-sufficient (having no needs) and it is you who are the needy ones. And if you turn back (from the truth), He will replace you with another people and they will not (behave) like you.
