وَلَا تَجْعَلُوا اللَّهَ عُرْضَةً لِّأَيْمَانِكُمْ أَن تَبَرُّوا وَتَتَّقُوا وَتُصْلِحُوا بَيْنَ النَّاسِ ۗ وَاللَّهُ سَمِيعٌ عَلِيمٌ (224)
(2:224) Do not use Allah's name for such oaths which are taken to keep back from virtue, piety and the welfare of mankind: *243
*243). Authentic Traditions indicate that if a person takes a vow and discovers later that righteousness and common good are best served by breaking that vow then he should do so. Expiation consists in either feeding or providing clothes for ten poor people, or setting free a slave, or fasting for three days (see 5: 89).
