Preparing for Hajj is one of the most important matters that help in performing Hajj in the right manner and ensuring that a pilgrim’s Hajj is accepted. Muslim scholars confirm that whoever wants to perform Hajj should first requite the rights of others by returning them to their rightful owners.
Almighty Allah says: “And eat up not one another’s property unjustly (in any illegal way), nor give bribery to the rulers (judges before presenting your cases) that you may knowingly eat up a part of the property of others sinfully.” (2: 188)
Almighty Allah also says: “O you who believe! Fulfill (your) obligations … ” (5: 1)
In addition, Abu Hurairah (may Allah be pleased with him) narrated that the Messenger of Allah (peace be upon him) said: “The claimants would get their claims on the Day of Judgment so justly that the hornless sheep would get its claim from the horned sheep.” Abu Hurairah also narrated : “Whoever takes the money of the people with the intention of repaying it, Allah will repay it on his behalf, and whoever takes it in order to spoil it, then Allah will spoil him.” (Reported by Al-Bukhari)
Moreover, Abu Hurairah narrated : “The Messenger of Allah (peace be upon him) said, ‘Do you know who the insolvent is? They (the Companions) said, ‘An insolvent man amongst us is one who has neither dirham with him nor wealth.’ He (the Prophet) said, ‘The insolvent of my nation would be the one who would come on the Day of Judgment with prayers and fasts and Zakah (alms) but (he would find himself bankrupt on that Day as he would have exhausted his stock of virtues since) he hurled abuses upon others, spoke slander against others, unlawfully consumed the wealth of others, shed the blood of others and beat others. Thus, every one of them would be given of his virtues ( i.e., his virtues would be credited to the account of those who suffered at his hands). And if his good deeds fall short to clear the account, then their sins would be transferred to his account and he would be thrown into the Hell-Fire’.” (Reported by Muslim)
There are many other Ahadith indicating that a Muslim should return the rights he had usurped to their rightful owners.
