Baha'u'llah's Miracle

The Prison was a garden of roses to him (Mirza Jafar-i-Yazdi), and his narrow cell a wide and fragrant place. At the time when we were in the barracks he fell dangerously ill and was confined to his bed. He suffered many complications, until finally the doctor gave him up and would visit him no more. Then the sick man breathed his last. Mirza Aqa Jan ran to Bahá'u'lláh, with word of the death. Not only had the patient ceased to breathe, but his body was already going limp. His family were gathered about him, mourning him, shedding bitter tears. The Blessed Beauty said, "Go; chant the prayer of Ya Shafi -- O Thou, the Healer -- and Mirza Ja`far will come alive. Very rapidly, he will be as well as ever." I reached his bedside. His body was cold and all the signs of death were present. Slowly, he began to stir; soon he could move his limbs, and before an hour had passed he lifted his head, sat up, and proceeded to laugh and tell jokes.

He lived for a long time after that, occupied as ever with serving the friends. This giving service was a point of pride with him: to all, he was a servant. He was always modest and humble, calling God to mind, and to the highest degree full of hope and faith. Finally, while in the Most Great Prison, he abandoned this earthly life and winged his way to the life beyond.
