He said, “O Mary, where did you get this from?” She said, “It is from God; God provides to whom He wills without reckoning.”

3:73And trust none except those who follow your religion.” Say, “Guidance is God’s guidance. If someone is given the like of what you were given, or they argue with you before your Lord, say, “All grace is in God’s hand; He gives it to whomever He wills.” God is Bounteous and Knowing.

3:75Among the People of the Book is he, who, if you entrust him with a heap of gold, he will give it back to you.

3:160If God supports you, there is none who can overcome you. But if He fails you, who is there to help you after Him? So in God let the believers put their trust.
