The challenge of Quran

Allah the Exalted has challenged Arabs and non-Arabs to
produce a Qur'an similar to the Divine one. The challenge was
reduced to ten Chapters, and yet they failed to do so. Finally,
Allah challenged them to produce a single Chapter
comparable to any of His. Although the Arabs at that time
were the masters of eloquence and rhetoric, they were
incapable of taking up the challenge. They realized that it
could never be from other than Allah , the Lord of the
worlds.
The difference between the miracles of the previous
Messengers, miracles proving their veracity, and that of
Allah's Messenger(pbuh) , is that theirs were effective during
their lifetime, whereas his miracle of the Qur'an has
remained and will remain effective, everlasting, and
unchallenged until the Day of Resurrection.

The Meaning of Islam

Islam is an Arabic word that denotes submission, surrender, and
obedience. As a religion, Islam stands for complete submission and
obedience to Allah—that is why it is called Islam. The other literal
meaning of the word "Islam" is "peace." This signifies that one can achieve
real peace of body and of mind only through submission and obedience to
Allah.2 Such a life of obedience brings peace of the heart and establishes
real peace in society at large.
