Undoubtedly, Hajj is best opportunity to wash one’s sins away and refine the soul. He / She who performs Hajj is supposed to be a model for others to be followed.

In fact,  those whom the Almighty favored to perform Hajj should be thankful to Allah and incessantly keep imploring and beseeching Him to accept their good deeds. This is crucial, for it reflects their belief that being so favored by the Almighty to accomplish Islam's fifth pillar is a favor that deserves gratitude and thank to Allah.

After returning from the holt places, the pilgrims should keep their mind and souls attached to the Almighty, remembering Him constantly for He says: So when you have accomplished your Manasik , remember Allah as you remember your forefathers or with a far more remembrance. (Al-Baqarah , 200)
He/ She who performed Hajj should be very keen to avoid evil and shameful deeds especially after Allah has forgiven all his previous sins, as a reward of performing Hajj for  “The reward of Hajj Mabrur (the one accepted by Allah) is nothing but Paradise.” (Reported by Muslim).

Upon returning home, the pilgrims should be conscious of Allah when performing all what Allah has instructed them to do of the other worships such as Salah (Prayers), Zakah, Fasting Ramadan, dutifulness to his parents, visiting kith and kin, being charitable and benevolent to Allah’s creatures, and the like of what the Muslim should do.

Hajj is considered as a blessing, the more it entails responsibility on which man will be asked concerning on the Day of Judgment in case the pilgrim misbehaves after returning from Hajj. Almighty Allah says, : Verily, Allah enjoins Al-'Adl (i.e. justice and worshipping none but Allah Alone - Islamic Monotheism) and Al-Ihsan [i.e. to be patient in performing your duties to Allah, totally for Allah's sake and in accordance with the Sunnah (legal ways) of the Prophet in a perfect manner], and giving (help) to kith and kin (o.e. all that Allah has ordered you to give them e.g., wealth, visiting, looking after them, or any other kind of help), and forbids Al-Fahsha' (i.e all evil deeds, e.g. illegal sexual acts, disobedience of parents, polytheism, to tell lies, to give false witness, to kill a life without right), and Al-Munkar (i.e all that is prohibited by Islamic law: polytheism of every kind, disbelief and every kind of evil deeds), and Al-Baghy (i.e. all kinds of oppression). He admonishes you, that you may take heed. (An-Nahl: 90)

Hajj is an obligation once in lifetime. Therefore, the pilgrim should take that as a golden opportunity which he/she will make use of for the rest of his/her life. He/she should keep remembering the holy places and all the rituals of Hajj for it will strengthen his faith and devotion to the Almighty.
