Al-Haafidh Ibn Rajab, may Allaah have mercy on him, was deeply attached to the works of Shaikh-ul-Islaam Ibn Taimiyyah, for he would issue legal rulings according to them and would constantly reference his books. This is since he served as a student under Ibn Qayyim al-Jawziyyah, the most outstanding student of Shaikh-ul-Islaam Ibn Taimiyyah, may Allah have mercy on all of them. But in spite of this, he (rahimahullaah) wasn’t a blind follower or a fanatical adherent (to his teacher). Rather, he would review, authenticate, verify and follow the evidences.
