Its forbidden in all Abrahamic religions. Meditation is from the Eastern religions.
Look at Sufism.
And no, meditation is not forbidden by any religion.
Our 5 time prayers are a form of meditation for us.
Other than that, it someone wants to, nothing wrong.
It's just sitting there in a peaceful state of mind.
Just no chanting, like some people like to do.
depends on what you're thinking when you're meditating. the five daily prayers that muslims perform is a type of meditation b/c you're supposed to concentrate on God only. you can't be distracted by your surroundings, or give your attention to something else while you're praying. you're supposed to completely set aside all your worldy thoughts for those few moments that you pray.
the prophet muhammad pbuh used to mediate in the cave of hera regularly before he was visited by the angel gabriel. He was sick of the evils and hypocrisy in the society he was living in and the strange ways of the pagans. He would go up to the cave and just ponder on his belief that there was only one supreme power. On one of the nights where he was meditating in this cave, he was visited by angel gabriel and thats when he was declared a prophet of God. Meditation and pondering is very characteristic of all the prophets of God. Thats what set them apart from the rest of the society. They refused to reform to the wrong ways and would always ponder and think about God and a supreme force controlling all things that go on in the world.
I will mention what the quran say's
"Beware! In remembrance of Allah do hearts find peace" (13:28) Salat, while offered properly and associated with meditation of Allah's presence and His watchfulness is the remembrance of the highest order and must provide peace. Qur'an proclaims: "Recite what is sent of the Book by inspiration to thee and establish Regular Salat: for Salat restrains from shameful and unjust deeds; and remembrance of Allah is the greatest (thing in life) without doubt. And Allah knows the (deeds) that ye do." (29:45)
First define the "concept of meditation".
* If by meditation you mean "a form of prayer in which a structured attempt is made to get in touch with and deliberately reflect upon the revelations of God", then muslims do meditate in the Qur'an which they consider the revelations of Allah.
* We christians meditate in God's Word, the Bible. We meditate in His promises, in what He has told us. The Bible several times urge us to meditate, for example:
Keep this Book of the Law always on your lips; meditate on it day and night, so that you may be careful to do everything written in it. Then you will be prosperous and successful.
Blessed is the one
who does not walk in step with the wicked
or stand in the way that sinners take
or sit in the company of mockers,
but whose delight is in the law of the LORD,
and who meditates on his law day and night.
My eyes stay open through the watches of the night, that I may meditate on your promises.
* If by "meditation" you mean a different concept then, probably no.
