When Haji Sahib was 16 years of age, he studied Sarf, Nahw, Farsi and one quarter of Mishkaat Shareef by Maulana Mamlook Ali Sahib (Rahmatullahi Alayhi) of Delhi.
Haji Imdadullah Muhajir Makki didn’t study Bukhari and the other books of Sihah Sitta, but Allah Ta’ala blessed Haji Imdadullah Muhajir Makki (Rahmatullahi Alayhi) with Ilm Ladunni
. One is that knowledge that a person acquires. He studies different subjects and books
. Another form of knowledge is from Allah Ta’ala without studying.
When Haji Imdadullah Muhajir Makki (Rahmatullahi Alayhi) would talk to the Ulama, he would resolve such intricate issues with the insight that Allah Ta’ala had given him. However, he would not use the Istilaahi language (academic terminologies). This is Ilm La Dunni.
this great personality was the shaykh of hazrat molana ashraf ali thanvi saheb r.a.
