In the name of Allah, the most Gracious, the most Merciful
All praise is due to Allah. We praise Him, we seek His help, we seek His forgiveness, and we seek refuge in Allah from the evil within ourselves and our evil deeds. Whoever Allah guides, there is none to misguide him. Whoever Allah leads astray, there is none to guide him. I testify there is no God but Allah alone, without any partners, and that Muhammad ﷺ (peace and blessings be upon him), is His servant and messenger.
Fear Allah and speak words as befitting. He will amend your deeds for you and forgive your sins. Whoever obeys Allah and His Messenger ﷺ has achieved a great triumph.” (33:70-71)
The truest word is the Book of Allah and the best guidance is the guidance of Muhammad ﷺ. The evilest matters are those that are newly-invented (in religion), for every newly-invented (religious) matter is an innovation. Every innovation (in religion) is misguidance, and every misguidance is in the Hellfire.
