An example of the Báb’s impact on some who were present during His brief public address at Vakil Mosque: - Mírzá Áqáy-i-Rikáb-Sáz

Still another was Mírzá Áqáy-i-Rikáb-Sáz. He became so enamoured of the Báb on that day that no persecution, however severe and prolonged, was able either to shake his convictions or to obscure the radiance of his love. He, too, attained the presence of Bahá’u’lláh in ‘Iráq. In answer to the questions which he asked regarding the interpretation of the Disconnected Letters of the Qur’án and the meaning of the Verse of Núr, he was favoured with an expressly written Tablet revealed by the pen of Bahá’u’lláh. In His path he eventually suffered martyrdom.

An example of the Báb’s impact on some who were present during His brief public address at Vakil Mosque: - Muhammad-Karím

A certain Muhammad-Karím who was among the congregation that Friday was likewise attracted by the Báb’s remarkable behaviour on that occasion. What he saw and heard on that day brought about his immediate conversion. Persecution drove him out of Persia to ‘Iráq, where, in the presence of Bahá’u’lláh, he continually deepened his understanding and faith. Later on he was bidden by Him to return to Shíráz and to endeavour to the best of his ability to propagate the Cause. There he remained and laboured to the end of his life.
