Morning

O people! Dispute not concerning My Cause, for ye shall never fathom the manifold wisdom of your Lord, nor shall ye ever gauge the knowledge of Him Who is the All-Glorious, the All-Pervading. Whosoever layeth claim to have known His Essence is without doubt among the most ignorant of all people. Every atom in the universe would charge such a man with imposture, and to this beareth witness My tongue which speaketh naught but the truth. Magnify My Cause and promulgate My teachings and commandments, for none other course beside this shall beseem you, and no other path shall ever lead unto Him. Would that ye might heed Our counsel! 

- Baha'u'llah  (Suriy-i-Haykal, 'The Summons of the Lord of Hosts')

Evening

Verily We made the revelation of verses to be a testimony for Our message unto you. Can ye produce a single letter to match these verses? Bring forth, then, your proofs, if ye be of those who can discern the one true God. I solemnly affirm before God, should all men and spirits combine to compose the like of one chapter of this Book, they would surely fail, even though they were to assist one another. [cf. Qur’án 17:90] 

- The Báb  (From Qayyum’ul-Asma; ‘Selections from the Writings of the Báb')
