2 Samuel 24:1 And again the anger of the LORD was kindled against Israel, and he moved David against them to say, Go, number Israel and Judah.

1 Chronicles 21:1 And Satan stood up against Israel, and provoked David to number Israel.

There is no contradiction but a completion of the story. It just shows that God uses Satan’s devise for His purposes. He uses man also.

Jeremiah 51:7 Babylon hath been a golden cup in the LORD’S hand, that made all the earth drunken: the nations have drunken of her wine; therefore the nations are mad.

Isaiah 13:17 Behold, I will stir up the Medes against them, which shall not regard silver; and as for gold, they shall not delight in it.
