Sayyidina Mu’azdh ibn Jabal (RA) reported that Allah’s Messenger (SAW) asked, “Do you realise what right Allah has over His slaves?” Mu’adh said, “Allah and His Messenger (SAW) know best.” He said, “His rights over them are that they should worship Him and not associate anything with Him.” He then asked, “Do you realise what is their right over Him if they perform that?” Mu’adh said, “Allah and His Messenger (SAW) know best.” He said, “That He should not punish them.”
