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.

playing of musical instruments. Is this an act of Satan?

Narrated Abu Malik Al-Ashari:

"The Messenger (pbuh) of Allah (SWT) said, "Some people of my Ummah will drink wine, calling it by other than its real name, merriment will be made for them through the playing of musical instruments and the singing of lady singers. Allah will cleave the earth under them and turn others into monkeys and swines. 
[Ibn Ma'jah Vol.5 Hadith No.4020]

Narrated Abu Amir or Abu Malik Al Ashari that he heard the Prophet saying, "From among my followers there will be some people who will consider illegal sexual intercourse, the wearing of silk, the drinking of alcoholic drinks and the use of musical instruments, as lawful. And there will be some people who will stay near the side of a mountain and in the evening their shepherd will come to them with their sheep and ask them for something, but they will say to him, 'Return to us tomorrow.' Allah will destroy them during the night and will let the mountain fall on them, and He will transform the rest of them into monkeys and pigs and they will remain so till the Day of Resurrection." 
[Sahih Al-Bukhari Vol.7 Hadith No.5590]

However, there are some Ahadith which indicate that it is permissible to beat the ‘daff’ i.e. the tambourine (which is open on one side and covered on the other). 

 Narrated Urwa on the authority of Aisha

“On the days of Mina, (11th, 12th, and 13th of Dhul-Hijjah) Abu Bakr came to her while two young girls were beating the tambourine (daff) and the Prophet was lying covered with his clothes. Abu Bakr scolded them. The Prophet uncovered his face and said to Abu Bakr, "Leave them, for these days are the days of 'Id and the days of Mina." 
Sahih Al-Bukhari Vol.2 Hadith No.987]

Narrated Ar Rabi (the daughter of Muawwidh bin Afra):

“After the consummation of my marriage, the Prophet came and sat on my bed as far from me as you are sitting now, and our little girls started beating the tambourines (daff) and reciting elegiac verses mourning my father, who had been killed in the battle of Badr. One of them said, ‘Among us is a Prophet who knows what will happen tomorrow.’ On that the Prophet said, ‘Leave this (saying) and keep on saying the verses which you had been saying before.’ [Sahih Al-Bukhari Vol.7 Hadith No.5147]

Therefore from the above evidence it is concluded that the use of musical instruments in general is forbidden in Islam, with the exception of the 'Daff'.

Music usually intoxicates a person and takes one away from the path of Allah (swt). Music engages a person’s mind and takes him/her away from the remembrance of his/her Creator and from realizing and focusing his/her attention on the purpose of his/her creation. In musical songs, most of the times the listeners even appreciate illogical, incorrect and blasphemous matter and content. A person will realize this when he starts pondering over the meaning of many Hindi and English songs, lyrics and ghazals. Here we find that it is because of music that the person’s mind is intoxicated and the person deviates from the straight path. And Allah Knows the Best.

why muslims did'nt burning the dead bodies?

Components of human body present in the soil
Elements that are present in the human body are present 
in lesser or greater quantity in the soil.
Hence it is more scientific to bury a dead body, as it 
easily gets decomposed and mixed in the soil.


No Pollution
Cremating (burning) the dead body leads to pollution of
the atmosphere which is detrimental to health and harmful
for the environment. There is no such pollution caused by burying 
a dead body.


Surrounding land becomes fertile
To cremate a dead body several trees have to be chopped, which 
reduces the greenery and harms the environment and the ecology. 
When dead bodies are buried, besides the trees being saved, the 
surrounding land becomes fertile and it improves the environment.


Economical
It is expensive to cremate a dead body when tons of wood have to be burned. Annually there is
a loss of crores of rupees, only because dead bodies are cremated in India. Burying dead
bodies is very cheap. It hardly costs any money.


Same land can be utilised for burying another body
The wood used for cremating a dead body cannot be reutilised for cremating another dead body
since it gets converted to ashes. The land used for burying a dead body can be reutilised for
burying another body after a few years since the human body gets decomposed and mixed in
the soil.
