Is Fasting is Obligatory on All Muslims in Ramadan Month?

God instituted Muslim fasting in Ramadan in the second year of the Hegira, this fast being one of the five pillars of Islam. Fasting is an ancient practice of purification and worship, and God says in the Quran:
 يا أيها الذين آمنوا كتب عليكم الصيام كما كتب علذ الذين من قبلكم لعلكم تتقون  

"O you believers, fasting is prescribed for you, as was prescribed for those before you, so that you may obtain the piety and the holy fear of God" (ALBAQARA, 183) 

Fasting in Islam consists of abstention Eating, drinking, marital relations, etc., from before dawn to sunset. It is not the sole purpose of fasting worship; There are innumerable benefits in relation to the senses and mood states. Self-control and moral conduct, and the mutual relationship between the members of human society are part of its advantages.
Wish you all a very Happy Ramadan Mubarak!
