Tafsir of Az-Zumar 39:33

والذي جاء بالصدق وصدق به

And he who has brought the truth and (those who) believed therein, Mujahid, Qatadah, Ar-Rabi` bin Anas and Ibn Zayd said, "The one who brought the truth was the Messenger.'' Abdur-Rahman bin Zayd bin Aslam said:

والذي جاء بالصدق

(And he who has brought the truth), means the Messenger of Allah

وصدق به

(and (those who) believed therein) means the Muslims.''

أوليك هم المتقون

they are those who have Taqwa. Ibn Abbas, may Allah be pleased with him, said, "They fear and shun Shirk.''
