The status of Hajj in Islam, and the conditions of it being obligatory

Hajj to the sacred House of Allaah is one of the pillars of
Islam and one of its most important fundamentals, because the Prophet
(peace and blessings of Allaah be upon him) said: “Islam is built on five
(pillars): the testimony that there is no god but Allaah and that Muhammad
is the Messenger of Allaah, establishing regular prayer, paying zakaah,
fasting Ramadaan and performing pilgrimage to the sacred House of Allaah.”  

It is obligatory according to the Book of Allaah and the
Sunnah of His Messenger (peace and blessings of Allaah be upon him),
and according to the consensus of the Muslims. Allaah says (interpretation
of the meaning): 

“And Hajj (pilgrimage to Makkah) to the House (Ka‘bah) is
a duty that mankind owes to Allaah, those who can afford the expenses (for
one’s conveyance, provision and residence) ; and whoever disbelieves [i.e.
denies Hajj (pilgrimage to Makkah), then he is a disbeliever of Allaah],
then Allaah stands not in need of any of the ‘Aalameen (mankind, jinn and
all that exists)”

[Aal ‘Imraan 3:97] 

The Prophet (peace and blessings of Allaah be upon him)
said: “Allaah has enjoined the Hajj upon you, so perform Hajj.” And the
Muslims are unanimously agreed upon that. It is something that no Muslim has
any excuse for not knowing. Whoever denies that it is obligatory and he is
one of those who live among the Muslims, is a kaafir. A person who fails to
do it out of negligence is in grave danger, because some of the scholars
said that such a person is a kaafir. This view is narrated in one report
from Ahmad, but the correct view is that neglecting deeds does not make a
person kaafir except in the case of prayer. ‘Abd-Allaah ibn Shaqeeq (may
Allaah have mercy on him) – who was one of the Taabi’een – said: “The
companions of the Messenger of Allaah (peace and blessings of Allaah be
upon him) did not regard omitting any action as kufr except prayer.” The one
who neglects to do Hajj until he dies is not a kaafir according to the
correct view, but he is in grave danger. 

The Muslim has to fear Allaah and hasten to perform Hajj once
he meets the conditions of it being obligatory, because we must hasten to
perform all obligatory duties unless there is evidence to the contrary. How
can a Muslim accept to forsake going to Hajj to the sacred House of Allaah
when he is able to do it and it is easy for him to get there? How can he
delay it when he does not know whether he will be able to get there after
this year? He may become unable to go after he was able, or he may become
poor after being rich, or he may die when Hajj was obligatory for him, then
his heirs may neglect to make it up on his behalf. 

The conditions of Hajj being obligatory are five: 

1 –  Being Muslim, the opposite of which is being a kaafir.
The kaafir is not obliged to do Hajj, rather if a kaafir were to do Hajj, it
would not be accepted from him. 

2 – Being an adult. If a person has not yet reached the age
of puberty, Hajj is not obligatory for him. If he does Hajj it is valid and
counts as a voluntary Hajj, and when he reaches adulthood he must do the
obligatory Hajj, because Hajj before puberty does not fulfil the
obligation. 

3 – Being of sound mind, the opposite of which is insanity.
The one who is insane is not obliged to do Hajj, and Hajj cannot be done on
his behalf. 

4 – Being free. A slave is not obliged to perform Hajj, but
if he does Hajj it is valid and counts as a voluntary Hajj. If he is set
free, it is obligatory for him to perform the obligatory Hajj, because Hajj
done before being set free does not fulfil the obligation. Some of the
scholars said that if a slave performs Hajj with the permission of his
master, this is valid and he does not have to repeat it. This view is more
correct. 

5 – Being able, financially and physically. In the case of a woman, this includes having a mahram. If she does not have a mahram, then she is not obliged to do Hajj. End quote.
