Why do Muslims go for Hajj?

VIRTUES OF HAJJ

Allah Ta'ala says in the Noble Qur'aan:
"And pilgrimage to the house (of Allah) is a duty man owes to Allah - upon those who can afford the journey, and for him who disbelieves, then indeed Allah is independent of His creation." (Aali Imraan 97)

Hadith one
Hadhrat Abu Hurairah (Radhiallaahu Anhu) reports that Rasulullah (Sallallaahu Alayhi Wasallam) said "Whoever performs Hajj for the pleasure of Allah and therein utters no word of evil, nor commits any evil deed, shall return from it free from sin as the day on which his mother gave birth to him." (MISHKAT).

Hadith Two
Hadhrat Abu Hurairah (Radhiallaahu Anhu) reports that Rasullulah (Sallallaahu Alayhi Wasallam) said: "Verily there shall be no reward for a righteous Hajj except Jannah." (MISHKAT).

Hadith three
Abdullah bin Mas'ood (Radhiallaahu Anhum) reports that Rasullulah (Sallallaahu Alayhi Wasallam) said: "Perform Hajj and Umrah one after the other for surely they (Hajj and Umrah) remove hunger and sins just as the furnace removes impurities from iron, gold and silver." (TIRMIZI/NISAI).

Hadith four:
Hadhrat Abbaas (Radhiallaahu Anhu) reports that Rasullulah (Sallallaahu Alayhi Wasallam) said "Whoever intends to perform Hajj should hasten, towards performing it." (ABU DAWOOD)

Hadhrat ibn Umar (Radhiallaahu Anhu) relates that Nabi
(Sallallahu-Alayhi-Wasallam) said "When you meet a Haaji, greet him, shake hands with him and request him to seek forgiveness on your behalf before he enters his home because he is (already) forgiven." (MASNAD AHMAD)

WARNING
Allah Ta'aala says:
"and spend of your substance in the way of Allah, and make not your own hands contribute to your destruction" (SURAH BAQARAH 24)

Hadhrat Abu Umama (Radhiallaahu Anhu) reports that Rasullulah (Sallallahu-Alayhi-Wasallam) said: "Whoever fails to perform Hajj while not being prevented from it by a valid necessity or by oppression from an unjust ruler or by severe illness and then passes away in such a state, has the choice to die as a Jew if he wishes or a Christian if he so wishes." (DAARIMI/MISHKAT)
