The Pillars of Islam are: To testify that there is no God but Allah and Mohammed is the Messenger of Allah; to perform the prayers; to pay the Zakat (alms); to fast in Ramadan, and to make the Pilgrimage to the House (Mecca) if you are able to do so.

So, Pilgrimage is one of the Pillars of Islam by the Holy Qu'ran, the Sunna (Hadith) and the unanimously. It is to be performed by every Muslim, released, matured, saint and able for both male and female and for once in the whole life.

The privilege of Pilgrimage to the Muslim is that it is one of the highly worships from the slave to his creator and his wish to receive God's forgiveness fur all thins and also, the gathering of the Muslims in one place in order to know about each other and to discuss and solve their difficulties and problems through this big gathering around the first (H9use) in Mecca. 

The Pilgrimage is always keen to stay away from the deeds prohibited by Allah whether in his thinking, behaviour, dressing or shape and stick to the doings and behaviour of Prophet Mohammed during the performance of Pilgrimage.
