Islam is the religion of peace

English Translation of Al-Quran
[24].Surah An-Nur [The
Light]
Ayat 55. Allah has promised those among you who believe, and do righteous good deeds, that He will certainly grant them succession to (the present rulers) in the earth, as He granted it to those before them, and that He will grant them the authority to practice their religion, that which He has chosen for them (i.e. Islam). And He will surely give them in exchange a safe security after their fear (provided) they (believers) worship Me and do not associate anything (in worship) with Me. But whoever disbelieved after this, they are the Fasiqun (rebellious, disobedient to Allah).

[Tafseer] of Ayat 55. Allah has promised, to those among you who believe and work righteous deeds, that He will, of asurety, grant them in the land, inheritance (of power), as Allah granted it to those before them; that Alalh will establish in authority their religion – the one which Allah has chosen for them; and that Allah will change (their state), after the fear in which they (lived), to one of security and peace: ´They will worship Allah (alone) and not associate aught with Allah. ´If any do reject Faith after this, they are rebellious and wicked. Three things are promised here, to those who have Faith and obey Allah’s Law: (1) that they will inherit power and authority on the land, not for any selfish purposes of theirs by way of favouritism, but in order that they may maintain Allah’s Law; (2) that the Religion of Right, which Allah has chosen for them, will be openly established, and will suppress all wrong and oppression; (3) that the righteous will live in peace and security, instead of having to suffer persecution, or leave their hearths and homes for the cause of Allah, or practise the rites of their Faith in secret. This verse was revealed about the time of the Battle of the Ditch (al Khandaq), also called the Battle of the Confederates ( al Ahzab), A.H. 4-5, we can imagine the comfort it gave to the Muslims who were besieged in Madinah by a force ten times their number. The Muslims then lived in a state of great suspense and danger, and under arms for days on end. (See 33:9-20). The security and authority they were promised came to them subsequently in abundant measures.
