A Muslim has to follow the two Revelations; the Qur'an and Sunnah
All praise is due to Allah Alone and peace and blessings be upon His Messenger, his family, and Companions.
Muslims are obliged to follow
the Qur'an and the Sunnah in addition to other established proofs deduced from both of them in case they are scholars. If not, they should follow the most trustworthy scholars. (Part No. 5; Page No. 36) May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
