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

April 8

O heedless one! [1] Rely not on thy glory, and thy power. Thou art even as the last trace of sunlight upon the mountain-top. Soon will it fade away as decreed by God, the All-Possessing, the Most High. Thy glory and the glory of such as are like thee have been taken away, and this verily is what hath been ordained by the One with Whom is the Mother Tablet. Where is he to be found who contended with God, and whither is gone he that gainsaid His signs, and turned aside from His sovereignty? Where are they who have slain His chosen ones and spilt the blood of His holy ones? Reflect, that haply thou mayest perceive the breaths of thine acts, O foolish doubter! Because of you the Apostle (Muhammad) lamented, and the Chaste One (Fátimih) cried out, and the countries were laid waste, and darkness fell upon all regions. O concourse of divines! Because of you the people were abased, and the banner of Islám was hauled down, and its mighty throne subverted. Every time a man of discernment hath sought to hold fast unto that which would exalt Islám, ye raised a clamor, and thereby was he deterred from achieving his purpose, while the land remained fallen in clear ruin. 
- Baha’u’llah  (‘Epistle to the Son of the Wolf’)
[1] Shaykh Muhammad-Taqi, known as Aqa Najafi, a son of Shaykh Muhammad-Baqir who was stigmatized by Baha’u’llah as 'Wolf'. After the death of his father in 1883, Aqa Najafi succeeded him as a leading mujtahid of Isfahan. He was an inveterate enemy and formidable opponent of the Cause of Bahá'u'lláh. (Adib Taherzadeh, ‘The Revelation of Baha’u’llah, vol. 4)
