Provided that the obedience is compulsory, it may be concluded that the apostles and "Ulil-Amr" () are sinless. Many verses in the Qur’an order men not to obey the unjust. Instead in the Qur’an Allah orders the believers to follow the apostle and the Ulul-Amr, and joins that obedience to obedience to Him, with the condition that no difference of opinion exists between Ulul-Amr and the Messenger, in any matter: ""O you who have believed, obey Allah and obey the Messenger and those in authority among you. And if you disagree over anything, refer it to Allah and the Messenger, if you should believe in Allah and the Last Day. That is the best and best in result.""
