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

October 28

In other instances, they [1] have idly contended that whereas the Day of Judgment is inevitable, it hath therefore been referred to as an event not of the future but of the past. How vain their sophistry! How grievous their blindness! They refuse to recognize the trumpet-blast which so explicitly in this text was sounded through the revelation of Muhammad. They deprive themselves of the regenerating Spirit of God that breathed into it, and foolishly expect to hear the trumpet-sound of the Seraph of God who is but one of His servants! Hath not the Seraph himself, the angel of the Judgment Day, and his like been ordained by Muhammads own utterance? Say: What! Will ye give that which is for your good in exchange for that which is evil? Wretched is that which ye have falsely exchanged! Surely ye are a people, evil, in grievous loss.
