The Shaykh’s mention of the meaning of (Whoever introduces a good practice in Islam... and whoever introduces a bad practice in Islam...) and the way to know them.

The Shaykh : “Whoever introduces” means whoever opens a path, a good path. Now we ask: What is the way to know the good practice so that we may emulate it and hold fast to it, and what is the way to know the bad practice so that we may avoid it and stay far from it? Is there any way other than the path that the Messenger (peace and blessings be upon him) brought, in the Book and the Sunnah? The answer is: nothing else, by his saying (peace and blessings be upon him): Thus, the path to our knowledge of the good practice and the bad practice is the Shari'ah, the Book and the Sunnah. This is a reality that no scholar can dispute or argue against, a reality, if his knowledge is derived from the Book of Allah and the hadith of the Messenger of Allah (peace and blessings be upon him).
