I’m sure I’ve gone into this before but it’s always good to remind myself at the very least.
So, aside from it being a commandment from Allah (swt)?
Fasting is not just about staying away from food and drink from dawn to sunset.
In the Qur’an, Suratul Baqarah Verse 183:
يَا أَيُّهَا الَّذِينَ آمَنُوا كُتِبَ عَلَيْكُمُ الصِّيَامُ كَمَا كُتِبَ عَلَى الَّذِينَ مِن قَبْلِكُمْ لَعَلَّكُمْ تَتَّقُونَ
O believers, fasting was prescribed to you as it was prescribed to those before you so that you may learn self-restraint (or learn to guard yourself against evil or learn God consciousness).
