…in the Qur’án are recorded all the calumnies and reproaches
uttered against Him, [Muhammad] as well as all the afflictions which He
suffered. Refer ye thereunto, that haply ye may be informed of that which hath
befallen His Revelation. So grievous was His plight, that for a time all ceased
to hold intercourse with Him and His companions. Whoever associated with Him
fell a victim to the relentless cruelty of His enemies.
- Baha’u’llah (‘The Kitab-i-Iqan’)
