10-49 Muhammad ibn al-Hassan - may God be pleased with him - narrated that Ahmad ibn Idris quoted Muhammad ibn Ahmad, on the authority of Aba Abdullah al-Razi, on the authority of Al-Hassan ibn Ali ibn Abi Uthman, on the authority of Muhammad ibn Himad al-Khazzaz, on the authority of Abdul Aziz al-Qaratisi,

“Abu Abdullah as-Sadiq (MGB) told me, ‘O Abdul Aziz! There are ten ranks of belief just like the steps of a ladder which one must climb up one after the other. One who has attained two of these ranks should not say to the one who has only attained the first rank, ‘You do not have faith.’ The same thing holds true up until the tenthrank. You should not consider anyone who has attained a rank lower than yourself to lack faith, so that those who have attained a higher rank than you have, do not consider you to lack faith. When you see someone who is in a lower rank than you are, kindly assist him up to your rank. Do not force upon him what he cannot tolerate, since you may hurt him this way. One who hurts a believer should help him get unhurt. Miqdad was in the eighth rank. Abuzar was in the ninth rank and Salman had attained the tenth rank of faith.’”
