Hajj - Reward & Benefits (Ahadith 1568 - 1569)


Bismillah.
Volume 3, Book 28, Number 45:
Narrated Abu Huraira (radiallaahu `anhu):
Allah's Apostle (sallallaahu `alayhi wasallam) said, "Whoever performs Hajj to this House (Ka'ba) and does not approach his wife for sexual relations nor commits sins (while performing Hajj), he will come out as sinless as a newly-born child. (Just delivered by his mother)."

Volume 3, Book 28, Number 46:
Narrated Abu Huraira (radiallaahu `anhu):
The Prophet (sallallaahu `alayhi wasallam) said, "Whoever performs Hajj to this Ka'ba and does not approach his wife for sexual relations nor commit sins (while performing Hajj), he will come out as sinless as a new-born child, (just delivered by his mother)."
No doubt, there is great reward in Hajj, for the one who does it with sincerity and in the prescribed manner. It is narrated in a saheeh report that the Prophet (blessings and peace of Allah be upon him) said:
An accepted pilgrimage brings no less a reward than Paradise.
And it was narrated that Abu Hurayrah (ra) said: The Messenger of Allah (blessings and peace of Allah be upon him) said:
The pilgrims performing Hajj and ‘Umrah are the guests of Allah; if they call upon Him He will answer them, and if they ask Him for forgiveness He will forgive them.
Narrated by al-Nasaa’i and Ibn Maajah.
There are some other benefits of Hajj as well, and here's an interesting compilation I found in my research:
  1. It is undertaking one of the pillars of Islam without which it is not complete. This is indicative of its importance and shows that Allah loves it.
  2. It is a kind of jihad for the sake of Allah; hence Allah mentions it after the verses of jihad. And it is proven in al-Saheeh that the Prophet (blessings and peace of Allah be upon him) said to ‘Aa’ishah (may Allah be pleased with her) when she asked him whether jihad is obligatory for women, “Yes, for them there is a jihad in which there is no fighting, Hajj and ‘Umrah.”
  3. In Hajj, remembrance of Allah is established, He is venerated and some rituals are carried out, such as reciting the Talbiyah, circumambulating the Ka‘bah (tawaaf), going between al-Safa and al-Marwah (saa‘i), standing in Arafat, staying overnight in Muzdalifah and stoning the Jamrah, along with what accompanies that of dhikr (remembrance of Allah), takbeer (proclaiming His greatness) and venerating Him. In the hadeeth it is narrated that the Prophet (blessings and peace of Allah be upon him) said: “Circumambulation of the Ka‘bah, going between al-Safa and al-Marwah and stoning the Jimaar have only been prescribed to establish the remembrance of Allah.”
  4. During Hajj, Muslims from all parts of the world come together and show their love for one another and get to know one another. That is also accompanied by exhortations, guiding towards truth and encouraging people to adhere to it.
  5. The Muslims demonstrate unity in time, place, actions and appearance. All of them stand in the different locations of Hajj at the same time, doing the same actions, wearing the same clothes (the izaar and rida’), with humbleness before Allah, may He be glorified and exalted.
  6. The season of Hajj brings a great deal of good in both spiritual and worldly terms, as the Muslims may benefit by coming together, learning from one another and doing business. Hence Allah, may He be exalted, said (interpretation of the meaning): “That they may witness things that are of benefit to them” [al-Hajj 22:28]. This includes both spiritual and worldly benefits.
  7. It includes offering both obligatory and mustahabb sacrifices, which demonstrate respect for the rituals prescribed by Allah, and eating from the meat and giving some in charity to the poor. 
The benefits and hidden wisdoms of Hajj are many.
