He was appointed as Sheikh ul-Islam by Alexander II of Russia after Fazil Iravani's resignation with a monthly pension of 1600 rubles on 15 October 1852.

He was described as a rather liberal-thinking cleric by Fatali Akhundzadeh[5] and contributed to Akinchi, first Azerbaijani language newspaper.

Like Akhundzadeh, he was a promoter of the Latin alphabet for Azerbaijani and defended the idea that it is not incompatible with Sharia and Islam.
