Surah 16

Surah 16:92

"Do not be like the one who unraveled her yarn, after (it was) firmly spun, (into) broken strands, (by) taking your oaths as a (means of) deception between you, because (one) community is more numerous than (another) community. God is only testing you by means of it. He will indeed make clear to you your differences on the Day of Resurrection."
