A reference to Ahmad, the Báb’s son, in Qayyúmu’l-Asma

And there is this further reference to Ahmad in the Qayyúmu’l-Asma:

All praise be to God Who bestowed upon the Solace of the Eyes, in His youth, Ahmad. We did verily raise him up unto God . . . O Solace of the Eyes! [1] Be patient in what thy God hath ordained for thee. Verily He doeth whatsoever He willeth. He is the All-Wise in the exercise of His justice. He is thy Lord, the Ancient of Days, and praised be He in whatever He ordereth. 

- The Báb (Provisional translation by Hand of the Cause Hassan Balyuzi; 'The Báb - The Herald of the Day of Days')

[1] The Báb refers to Himself time and again in this Book as ‘Qurratu‘l-‘Ayn‘—the Solace of the Eyes.
