Baha’u’llah brings to our attention an amazing point concerning “obligatory prayer and fasting”

Be not neglectful of obligatory prayer and fasting. He who faileth to observe them hath not been nor will ever be acceptable in the sight of God. Follow ye wisdom under all conditions. He, verily, hath bidden all to observe that which hath been and will be of profit to them. He, in truth, is the All-Sufficing, the Most High. (Baha’u’llah, Compilation on ‘The Importance of Obligatory Prayer and Fasting’, prepared by Research Department of the Universal House of Justice)
