Narrated Mu'adh bin Jabal (Radhi-Allah-hu 'anhu):
The Prophet (salAllahu alayhi wa sallam) said:
"O Mu'adh! Do you know what Allah's Right upon His slaves is?"
I said, "Allah and His Apostle know best."
The Prophet (salAllahu alayhi wa sallam) said, "To worship Him (Allah) Alone and to join none in worship with Him (Allah).
Do you know what their right upon Him is?"
I replied, "Allah and His Apostle know best."
The Prophet (salAllahu alayhi wa sallam) said, "Not to punish them (if they do so)."
