Hajj a Pillar of Islam:
Ibn Umar reported: The Messenger of Allah, peace and blessings be upon him, said, “Islam is built upon five: to worship Allah and to disbelieve in what is worshiped besides him, to establish prayer, to give charity, to perform Hajj pilgrimage to the house, and to fast the month of Ramadan.”
Source: Ṣaḥīḥ al-Bukhārī 8, Ṣaḥīḥ Muslim 16
The Messenger of Allah (ﷺ) delivered a Khutbah and said, “O people! Hajj (pilgrimage to the House of Allah) has been made incumbent upon you, so perform Hajj.” [Muslim]
According to another Hadith:
“Whoever performs Haj for the sake of Pleasing Allah, and does not utter any disgusting remarks of sexual nature, nor commits any evil, will return as free from sins as the day in which his mother gave birth to him”.
