Distinguishing between Islam and Faith.

The Shaykh : And you must know with me, as well, that there is Islam and there is Faith. Islam encompasses practical rulings, while Faith pertains to matters of the heart. The disbeliever is the one who declares his disbelief with his tongue and fights the caller to Islam, but the hypocrite displays Islam and says: "I bear witness that there is no god but Allah and that Muhammad is the Messenger of Allah," but in his heart he is a denier and a disbeliever. And he is as He, the Exalted, said on the Day of Resurrection: .
So when we find a ruler who is negligent in applying the Shari'ah rulings, whether much or little, but we find that he preserves prayer, for example, then it is not permissible to declare him a disbeliever. Why? Because we have not heard from him a denial of Islam or of some of the rulings of Islam that he lived through for a long time. For that reason, Ibn Abbas (may Allah be pleased with him) said in his interpretation of the aforementioned verse: He said in its interpretation: "Disbelief less than disbelief," "Disbelief less than disbelief." The verse, as the Imam of the exegetes, "Muhammad ibn Jarir al-Tabari," explains in his famous "Tafsir": "It was revealed concerning the Jews and the Christians who do not judge by what Allah has revealed," meaning by the Shari'ah of Islam.
