Hi,my name is Rahman!
Founder of MIG (Moderate Islam Global), The Prophet of Islam also did his part for promoting moderation by advising one of his followers to observe optional fasting on alternative days in preference to his enthusiasm to fast on daily basis.
The extremism of fasting for days in a row could not only bring unnecessary hardship in violation of Quranic provision (22:78) but also undermine his other priorities like living normal conjugal life, making honest income for family etc. Liberalism, on the other hand, may mean a deviation from the essentials of Islam. The moderate approach as envisioned in the Quran therefore appears to be the better and most beneficial option.
