Mírzá Músá: Bahá’u’lláh’s faithful brother, also known as Áqáy-i-Kalím – a brief account of his life by 'Abdu'l-Baha

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 Tihrán 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.

Táhirih proclaims “the Day of Resurrection” – ‘Abdu’l-Baha describes the circumstances

In Badasht there was a field with a stream running through it and gardens to either side. Quddús remained concealed in one of the gardens, and Táhirih resided in the other. A tent had been pitched for Bahá’u’lláh on that field, and the other believers were also housed in tents erected on the same field. In the evenings Bahá’u’lláh, Quddús, and Táhirih would meet. Bahá’u’lláh made a solemn agreement with them that the truth of the Cause would be proclaimed at Badasht, but no specific day was designated.

Then, by chance, Bahá’u’lláh fell ill. As soon as he was informed, Quddús emerged from his concealment and entered Bahá’u’lláh’s tent. Táhirih sent a message saying: “Either bring Bahá’u’lláh to the garden where I reside or I will come myself.” Quddús said: “Bahá’u’lláh is unwell and cannot come”, which was a signal. Táhirih, seizing upon the opportunity, arose and, unveiled, came forth from the garden. She proceeded towards the tent of Bahá’u’lláh crying out and proclaiming: “I am the Trumpet-blast; I am the Bugle-call!”—which are two of the signs of the Day of Resurrection mentioned in the Qur’án. Calling out in this fashion, she entered the tent of Bahá’u’lláh. No sooner had she entered than Bahá’u’lláh instructed the believers to recite the Súrih of the Event from the Qur’án, a Súrih that describes the upheaval of the Day of Resurrection.
