Fasting is one of the five pillars of Islam. There is also a verse in the Quran that describes fasting for all Muslims who are mature and healthy to do so for the full day(from sunrise to sunset).So Muslims fast as an act of worship, a chance to get closer to Allah.
Fasting in Ramadan is Farj for Muslims.Now it is Ramadan and we have a chance to get rid of the sins.If you are Muslim,keep fasting and pray to Allah.We should also pray for the pandemic situation of covid.
Abide by the health rules
Keep distance
Stay home
Stay safe
AFAIK, Ramadhan is not only about fasting it is also about helping other people. Intermittent fasting is good for health so it is also scientifically a reason to do it.
