Baha'u'llah & the New Era by -J. Esslemont- 1 Para

After His return from this retirement, His fame became greater than ever and people flocked to Baghdad.. to see Him.. The Mullas, however, took up a hostile attitude and persistently plotted to effect His overthrow..
he (emissary of Mullas) asked that some miracle should be produced as a proof. Baha'u'llah.. (declared) that if the Mullas would agree regarding some miracle to be performed, and would sign and seal a document to the effect that on the performance of this miracle they would confess the validity of His mission and cease to oppose Him, He would furnish the desired proof or else stand convicted of imposture.. They feared the truth and fled from the daring challenge. This.. only spurred them on to devise fresh plots.. (28:2)
