The Messengers and the City

Do not be like the woman who unravels her thread after spinning it tightly, using your oaths deceitfully to gain advantage over others. Allah only tests you through this, and He will clarify for you on the Day of Judgment what you used to dispute.

16:92And be not like unto her who unravelleth the thread, after she hath made it strong, to thin filaments, making your oaths a deceit between you because of a nation being more numerous than (another) nation. Allah only trieth you thereby, and He verily will explain to you on the Day of Resurrection that wherein ye differed.
