Readings from the Quran [18]: Unravvelling Yarn

God enjoins justice, kindness and charity to one's kindred,
and forbids lewdness, reprehensible conduct and oppression.
He admonishes you so that you may take heed.

Keep faith with God when you make a pledge.
You shall not break your oaths after you have sworn them:
for by swearing in His name you make God your surety.
God has knowledge of all your actions.

Do not -like the woman who unravels the thread she has firmly spun -
take oaths with mutual deceit and break them on finding yourselves superior in numbers.
In this, God puts you to the proof.
On the Day of Resurrection He will resolve your differences for you.

Quran 16: 90-92
