Ottoman history gives a record of many commanders, many men of knowledge and science who had formerly been Christians and who eventually accepted Islam and subsequently performed many services to the religion.
Ismail Hakki Effendi (rahima-hullahu ta’ala) passed away in Bursa in the year 1137 . His explanation of the Qur’an al-karim, namely Ruh-al-bayan, which consists of ten volumes, is esteemed highly by Islamic savants (rahima-humullahu ta’ala) all over the world. He said after finishing the interpretation of the sixth juz: “My shaikh [master, teacher] was the scholar of his time. When he was told that some Jews and Christians behaved honestly and truly and did favors for everybody, he responded, “Being so is a sign which is peculiar to those who will be given eternal felicity. It is hoped that those who have such qualities will attain iman (faith) and tawhid and that their end will be salvation. ” This quotation from a book of explanation is another proof for our words above.
