The human being is the only creature who has been distinguished from other creatures with the instinct of knowing right from wrong. He is, therefore, the only one who is expected to be the perfect image of his Creator. That is why the objective of his life is to know his Creator and become a perfect image of his attributes, as Allah says in the Holy Qur'an:
"I have not created jins and humans but, for my worship"

SALAT or the method of worship is the main media through which a human can establish a relationship with his Creator and it is one of the main doors which leads to his complete submission to Allah's will. 

Salat also prevents him from wrongdoings. Allah says:
"Surely prayer restrains one from indecency and manifest evil." Which shows that Salat or prayer is a guarantee from Allah that if a worshipper observes prayer with all its conditions, he will be safe from evils, manifest or hidden, small or great. The Holy Prophet (peace be on him) asked to the companions, "if one of you had a stream running by his door and he takes a bath in it five times a day, would any dirt be left on him?." They replied! "No dirt would be left on him". The Holy Prophet said: "This is the case with Salat (the five daily prayers) Allah makes the Salat wipe out his sins". 
When we reflect on the creation of the universe and the law that governs it and the design and variety that pleases our eyes, we naturally are convinced of existence and greatness of Allah.

Allah says in the Holy Quran:
"In the creation of the heavens and the earth and in the alternation of the night and the day there are indeed signs for men of understanding;" Those who remember Allah while standing, sitting, and lying on their sides, and ponder over the creation of the heavens and the earth: "Our Lord, Thou hast not created this in vain; nay, Holy art Thou; save us, then, from the punishment of the Fire." (Aal-e-Imran, v19l-192)

This verse beautifully tells us that when a worshipper reflects upon the structure of the Universe he becomes overwhelmed with the greatness of its Creator. The ENTITY Who created such an awe-inspiring structure with such detailed arrangement and accuracy. He is alone to be worshipped and so right for protection.

There are five daily prayer services participation in which is obligatory. This may seem a little too much, but it is all a matter of comparative values. Those who realize the true value of prayer through experience are convinced that time spent in it is occupied much more beneficially than that spent in other pursuits.

There is no ordained priesthood in Islam. Every Muslim can be Imam (who leads congregational prayer) and can deliver a sermon. The members of the congregation may select, and for this purpose, they should choose one from among themselves who knows the Holy Quran better than the others. No vestment is prescribed for the Imam nor any special dress for the congregation. All that needed is the body and the head should be decently and cleanly covered.
