The sentence" It is on people for the sake of Allah ..." adding the definition of" disbelieve"( infidelity )for people who renounce the obligatory Hajj, clears its extraordinary importance in Islam.

It is interesting that in interpretation of the holy verse 72 of Isra Sura:

وَ مَنْ كانَ فى هذِهِ اعْمى فَهُوَ فِى الْاخِرَةِ اعْمى وَ اضَلُّ سَبيلًا.

And anyone who had been blind( from seeing Allah )in this world, will be blind in hereafter and more aberrant from the path".

It has been quoted from Imam Sadiq( a. s. )that one of the meanings of the verse is a person who postpones his obligatory Hajj continuously until his death arrives) he will be blind in hereafter (. 1

It has been mentioned in another Hadith:" Anyone who renounces his obligatory Hajj without any excuse will be rewoken as Jew or Christian".

And in change, it has been mentioned great rewards for Hajj in Islam that its examples are few for other acts.

1- This Hadith and future ones have been quoted by the late Mohaghegh Yazdi in" al- Urwat al- Wusqa" in the book of Hajj and the late Sheikh Hurr Ameli and other great scholars in the book" Wasael al- Shiaa" and other famous Hadith books.
