“Recite ye the verses of God every morn and eventide.” (Bahá’u’lláh, ‘The Kitáb-i-Aqdas’)

April 3

Behold how the sovereignty of Muhammad, the Messenger of God, is today apparent and manifest amongst the people. You are well aware of what befell His Faith in the early days of His Dispensation. What woeful sufferings did the hand of the infidel and erring, the divines of that age and their associates, inflict upon that spiritual Essence, that most pure and holy Being! How abundant the thorns and briars which they have strewn over His path! It is evident that that wretched generation, in their wicked and satanic fancy, regarded every injury to that immortal Being as a means to the attainment of an abiding felicity; inasmuch as the recognized divines of that age …all treated Him as an impostor... Such sore accusations they brought against Him that in recounting them God forbiddeth the ink to flow, Our pen to move, or the page to bear them. These malicious imputations provoked the people to arise and torment Him…

For this reason did Muhammad cry out: “No Prophet of God hath suffered such harm as I have suffered.” And in the Qur’án are recorded all the calumnies and reproaches uttered against Him, as well as all the afflictions which He suffered.
