The obligation of Hajj is firmly established through the Qur’an, the Sunnah of the Prophet Muhammad (peace be upon him), and the unanimous consensus of Muslim scholars throughout history.
Whoever denies the obligation of Hajj is considered to have left the fold of Islam. And whoever neglects it out of laziness or indifference, despite acknowledging its obligation, is committing a grave sin and is in serious danger of falling into disbelief.
Allah the Almighty says in the Qur’an:
“Pilgrimage to the House is a duty owed to Allah by all people who are able to undertake it. And whoever disbelieves—then surely Allah is free of need from all creation.”
(Surah Aal `Imran, 3:97)
The Prophet Muhammad (peace be upon him) stated that:
“Islam is built upon five pillars…”
—one of which is the pilgrimage to the sacred House (Hajj). Without fulfilling all five, one’s Islam remains incomplete.
Furthermore, Umar ibn Al-Khattab (may Allah be pleased with him) said:
“I was about to send envoys to check on those who had the means to perform Hajj but did not do so, and to collect the Jizyah from them; they are not Muslims, they are not Muslims.”
This reflects the seriousness with which the early generations of Islam viewed the obligation of Hajj for those who are physically and financially capable.
