32-20 Muhammad ibn Al-Hassan ibn Ahmad ibn al-Waleed - may God be pleased with him - narrated that Muhammad ibn Al-Hassan al-Saffar quoted on the authority of Muhammad ibn Isa that Al-Hassan al-Nadhr asked Ar-Ridha’ , “What is the reason they say the phrase God is the Greatest five times over a person’s corpse?” He  said, “On the surface it seems that this is because it has been taken from the five daily prayers. However, there is another reason for that. Indeed the Honorable the Exalted God has made it incumbent upon His servants to perform five obligatory deeds: praying, paying the alms-tax, fasting, going on the Hajj pilgrimage, and accepting the Mastery (of the Immaculate Imams). Therefore, He has established saying God is the Greatest once for eachof the obligatory deeds. If he has accepted the Mastery (of the Immaculate Imams), then it should be said five times. However, if he has not accepted it, the phrase God is the Greatest should be said only four times. That is why when one of you (the Shiites) die, the phrase is said five times. However, when one who disagrees with you (i.e. is not one of the Shiites) dies, the phrase is said only four times.
