Whoever performs Hajj while he continues to commit Acts of Disobedience
Question :
What is the ruling of the Hajj of the person who persistently commits an act of disobedience or he continues to commit a minor sin?
Answer:
His Hajj is correct if he is a Muslim, however it is deficient and he is required to repent to Allâh from all sins, especially during the time of the Hajj and in this City of Security (Makkah). Whoever repents, Allâh will accept his repentance. This is due to the Statement of Allâh:
"And all of you repent to Allah, O you believers, so that perhaps you will be successful."
And His Statement:
"O you who believe, repent to Allah in sincere repentance. Maybe your Lord will expiate your bad deeds from you and enter you into Gardens (of Paradise) with rivers flowing beneath them."
The sincere repentance is that which includes ceasing the performance of the sins, avoiding them out of respect for Allâh and fear of His punishment, along with feeling sorry for what passed of them, and true resolve not to return to them. From the completion of repentance is to return the rights of injustices to those who deserve them, if there was some injustice regarding a soul or some wealth or a person or honor or seeking pardon from the people. May Allâh help the Muslims to do what contains rectification of their hearts and their actions, and may He bless them and us with true repentance from all sins. Verily, He is Most Generous, Most Noble.
