“Quddus, immortalized by Him [the Bab] as Ismu'llahi'l-Akhir (the Last Name of God); on whom Bahá'u'lláh's Tablet of Kullu't-Ta'am later conferred the sublime appellation of Nuqtiy-i-Ukhra (the Last Point); whom He elevated, in another Tablet, to a rank second to none except that of the Herald of His Revelation; whom He identifies, in still another Tablet, with one of the ‘Messengers charged with imposture’ mentioned in the Qur'án; whom the Persian Bayan extolled as that fellow-pilgrim round whom mirrors to the number of eight Vahids revolve; on whose ‘detachment and the sincerity of whose devotion to God's will God prideth Himself amidst the Concourse on high;’ whom 'Abdu'l-Bahá designated as the ‘Moon of Guidance;’ and whose appearance the Revelation of St. John the Divine anticipated as one of the two ‘Witnesses’ into whom, ere the ‘second woe is past,’ the ‘spirit of life from God’ must enter”
-Shoghi Effendi ('God Passes By')
Such a person showed incredible humility towards the Bab as documented below by the great historian Nabil:
"Upon His arrival in Jaddih, the Báb donned the pilgrim's garb, mounted a camel, and set out on His journey to Mecca [to perform His pilgrimage]. Quddus, however, notwithstanding the repeatedly expressed desire of his Master, preferred to accompany Him on foot all the way from Jaddih to that holy city. Holding in his hand the bridle of the camel upon which the Báb was riding, he walked along joyously and prayerfully, ministering to his Master's needs, wholly indifferent to the fatigues of his arduous march. Every night, from eventide until the break of day, Quddus, sacrificing comfort and sleep, would continue with unrelaxing vigilance to watch beside his Beloved, ready to provide for His wants and to ensure the means of His protection and safety."
- Nabil (The Dawn-Breakers, translated and edited by Shoghi Effendi)
