“When the retinue of Bahá’u’lláh left Baghdad for Constantinople, [as they had been exiled,] He was accompanied by a great crowd of people. Along the way, they met with famine conditions. These two souls strode along on foot, ahead of the howdah in which Bahá’u’lláh was riding, and covered a distance of seven or eight farsakhs every day. Wayworn and faint, they would reach the halting-place; and yet, weary as they were, they would immediately set about preparing and cooking the food, and seeing to the comfort of the believers. The efforts they made were truly more than flesh can bear. There were times when they had not more than two or three hours sleep out of the twenty-four; because, once the friends had eaten their meal, these two would be busy collecting and washing up the dishes and cooking utensils; this would take them till midnight, and only then would they rest. At daybreak they would rise, pack everything, and set out again, in front of the howdah of Bahá’u’lláh. See what a vital service they were able to render, and for what bounty they were singled out: from the start of the journey, at Baghdad, to the arrival in Constantinople, they walked close beside Bahá’u’lláh; they made every one of the friends happy; they brought rest and comfort to all; they prepared whatever anyone asked.“
