Abdul Ghani was quite a multilingual person. He spoke in Bengali, Urdu, English, and Persian. He learnt Arabic and Persian at home, and English at Dhaka Collegiate School, where he was the student of the very first batch. He is known as patron of Urdu and Persian literature in Dhaka. He observed the Shi'a Remembrance of Muharram, and contributed to renovate Hoseni Dalan, the Shi'ite centre in Dhaka, though he was a Sunni himself. He also had close relations with the Hindu, Armenian and European community.
