Comparing Quran with the Bab and Baha'u'llah's writings

The Holy Qur’an was one single volume of 6300 verses. Then in one lightning stroke came the Báb, of whose revealed flood of divine knowledge Bahá’u’lláh Himself writes:

“… the verses which have rained from this Cloud of divine mercy have been so abundant that none hath yet been able to estimate their number. A score of volumes are now available. How many still remain beyond our reach! How many have been plundered and have fallen into the hands of the enemy, the fate of which none knoweth.”[1]

The Báb Himself clarified the scale of His own work, referring to Himself in the third person:

“Now, following His manifestation, although He hath, up to the present, revealed no less than five hundred thousand verses on different subjects, behold what calumnies are uttered, so unseemly that the pen is stricken with shame at the mention of them. But if all men were to observe the ordinances of God no sadness would befall that heavenly Tree.”[2]
