We read in a Hadith from Imam Sadiq( a. s. ):" Persons who perform Hajj and Umrah are guests of Allah, He will give them anything that they want and any pray that they say will be accepted, and if they make an intercession about a person it will be accepted ... and if they die in this way Allah will forgive all of their sins".

Also, we read in another Hadith that:

انَّ الْحَجَّ المَبْرُورَ لا يَعْدِلُهُ شَى‌ءٌ وَ لا جَزاءَ لَهُ الَّا الجَنَّة.

Nothing compares with the accepted Hajj and it has no reward other than heaven!"

وَ انَّ الْحاجَّ يَكُونُ كَيَوم وَلَدَتْهُ امُّه.

Person who performs Hajj purifies himself from sins like the day that he was born".

And this is the greatest gift, and the best honor and the highest reward.
