As followers of Jesus, we should always be sharing our faith with those around us. There are now around 2 billion Muslims in the world. Having some knowledge of the Qur’an can help open doors to understand them better. We will always rely on the Bible as our authority (2 Timothy 3:16), praying that it will speak to many (Romans 10:17) and draw them to Himself.
(some have considered this to be the Prophet Isaiah or some righteous man)
21:85. And (remember) Isma’il, Idris, and Zul-kifl, all (men) of constancy and patience;
38:48. And commemorate Isma’il, Elisha, and Zul-Kifl: Each of them was of the Company of the Good.
