When he was twelve years old, his father, Sadruddin Akhund, decided to set off for the Hajj pilgrimage to Arabia.

Whilst at Hooghly, Ahmad pledged bay'ah to Mohammad Abu Bakr Siddique of Furfura Sharif in 1895.

[14] After receiving khilafat (spiritual succession) from his murshid Mohammad Abu Bakr Siddique, Ahmad returned to his village.
