Jináb-i-Mírzá Músá was the true brother of Bahá’u’lláh, and from earliest childhood he was reared in the sheltering embrace of the Most Great Name. He drank in the love of God with his mother’s milk; when yet a suckling, he showed an extraordinary attachment to the Blessed Beauty. At all times he was the object of Divine grace, favor and loving-kindness. After their distinguished father died, Mírzá Músá was brought up by Bahá’u’lláh, growing to maturity in the haven of His care. Day by day, the youth’s servitude and devotion increased. In all things, he lived according to the commandments, and he was entirely severed from any thoughts of this world.

Like a bright lamp, he shone out in that Household. He wished neither rank nor office, and had no worldly aims at all. His one supreme desire was to serve Bahá’u’lláh, and for this reason he was never separated from his Brother’s presence. No matter what torments the others inflicted, his loyalty equaled the cruelty of the rest, for he had drunk the wine of unadulterated love.

Then the voice was heard, crying out of Shíráz, and from a single utterance of Bahá’u’lláh’s his heart was filled with light, and from a single gust that blew over the gardens of faith, he caught the fragrance. At once, he began to serve the friends. He had an extraordinary attachment to me, and was at all times concerned for my well-being. In Ṭihrán he occupied himself day and night with propagating the Faith and gradually became well known to everyone; habitually he spent his time in the company of blessed souls.

Bahá’u’lláh then left Ṭihrán, journeying to ‘Iráq, and of His brothers the two who were in His company were Áqáy-i-Kalím[51] and Mírzá Muḥammad-Qulí. They turned their faces away from Persia and the Persians, and closed their eyes to comfort and peace; in the Beloved’s path they chose with all their hearts to bear whatever calamity should be their lot.

Thus they arrived in ‘Iráq. During the days when Bahá’u’lláh had vanished from sight, that is, when He was on the journey to Kurdistán, Áqáy-i-Kalím lived on the edge of an abyss; his life was constantly in danger, and each day that passed was worse than the one before; still, he bore it all, and knew no fear. When at last the Blessed Beauty returned out of Kurdistán, Áqáy-i-Kalím resumed his post by the Holy Threshold, rendering every service within his power. For this he became known far and wide. At the time when Bahá’u’lláh left Baghdád for Constantinople, Áqáy-i-Kalím was with Him and continued to serve along the way, as he did on the further journey from Constantinople to Adrianople.

It was during the sojourn in this latter city that he detected from Mírzá Yaḥyá the odor of rebellion. Day and night he tried to make him mend his ways, but all to no avail. On the contrary, it was astonishing how, like a deadly poison, the temptings and satanic suggestions of Siyyid Muḥammad worked on Mírzá Yaḥyá, so that Áqáy-i-Kalím finally abandoned hope. Even then he never ceased trying, thinking that somehow, perhaps, he could still the tempest and rescue Mírzá Yaḥyá from the gulf. His heart was worn away with despair and grief. He tried everything he knew. At last he had to admit the truth of these words of Saná’í:

If to the fool my lore you’d bring,

Or think my secrets can be told

To him who is not wise—

Then to the deaf go harp and sing,
