"WHAT IS ISLAM?"
"WHAT IS FAITH?"
Allah's Messenger (ﷺ) replied, 'Faith is to believe in Allah, His angels, (the) meeting with Him, His Apostles, and to believe in Resurrection."
[Sahih al-Bukhari: Book 2, Hadith 43]
"You are the best nation produced [as an example] for mankind. You enjoin what is right and forbid what is wrong and believe in Allah . If only the People of the Scripture had believed, it would have been better for them." [Quran: Chapter 3, Verse 110]
