(Fasting Emphasized and Modified*)
O you who believe, fasting is decreed for you, as it was decreed for those before you, that you may attain salvation.
يٰأَيُّهَا الَّذينَ ءامَنوا كُتِبَ عَلَيكُمُ الصِّيامُ كَما كُتِبَ عَلَى الَّذينَ مِن قَبلِكُم لَعَلَّكُم تَتَّقونَ
yaa ayyuhal lazeena aamanoo kutiba ‘alaikumus Siyaamu kamaa kutiba ‘alal lazeena min qablikum la’allakum tattaqoon
*2:183-187 Like all duties in Submission, fasting was decreed through Abraham (22:78, Appendices 9 & 15). Prior to revelation of the Quran, sexual intercourse was prohibited throughout the fasting period. This rule is modified in 2:187 to allow intercourse during the nights of Ramadan.
