Fast to Develop Piety

يَا أَيُّهَا الَّذِينَ آمَنُواْ كُتِبَ عَلَيْكُمُ الصِّيَامُ كَمَا كُتِبَ عَلَى الَّذِينَ مِن قَبْلِكُمْ لَعَلَّكُمْ تَتَّقُونَ

(2:183) O Believers, the Fast has been made obligatory on you just as it was prescribed for the followers of the Prophets before you. It is expected that this will produce piety in you.
