Quran and Iqan

Baha'u'llah wrote in Kitab Iqan; Book of Certitude:
.......And likewise, He saith: “Say, O people of the Book! do ye not disavow us only because we believe in God and in what He hath sent down to us, and in what He hath sent down aforetime, and because most of you are doers of ill?” Qur’án 5:62. How explicitly doth this verse reveal Our purpose, and how clearly doth it demonstrate the truth of the testimony of the verses of God! This verse was revealed at a time when Islám was assailed by the infidels, and its followers were accused of misbelief, when the Companions of Muḥammad were denounced as repudiators of God and as followers of a lying sorcerer. In its early days, when Islám was still to outward seeming devoid of authority and power, the friends of the Prophet, who had turned their face toward God, wherever they went, were harassed, persecuted, stoned and vilified. At such a time this blessed verse was sent down from the heaven of divine Revelation. It revealed an irrefutable evidence, and brought the light of an unfailing guidance. It instructed the companions of Muḥammad to declare the following unto the infidels and idolators: “Ye oppress and persecute us, and yet, what else have we done except that we have believed in God and in the verses sent down unto us through the tongue of Muḥammad, and in those which descended upon the Prophets of old?” By this is meant that their only guilt was to have recognized that the new and wondrous verses of God, which had descended upon Muḥammad, as well as those which had been revealed unto the Prophets of old, were all of God, and to have acknowledged and embraced their truth. This is the testimony which the divine King hath taught His servants......
