The best talk (speech) is Allah's Book 'Qur'an), and the best way is the way of Muhammad, and the worst matters are the heresies (those new things which are introduced into the religion); and whatever you have been promised will surely come to pass, and you cannot escape (it).
Holding Fast to the Qur'an and Sunnah
Sahih al-Bukhari 7277
The Excellence of Divine Revelation
The noblest speech is Allah's Book, for it contains perfect guidance, eternal wisdom, and divine legislation. Unlike human discourse, the Qur'an's eloquence, truth, and spiritual power remain unmatched throughout time.
The Prophetic Methodology
The best path is that of Prophet Muhammad (peace be upon him), whose Sunnah provides the practical implementation of Qur'anic teachings. His way represents moderation, mercy, and complete submission to Allah's will.
Warning Against Religious Innovation
The most reprehensible matters are newly-invented practices in religion, as they constitute deviation from pure revelation. Every innovation (bid'ah) leads astray, and every straying leads to Hellfire.
Divine Promise and Human Accountability
All that Allah has promised - both reward for obedience and punishment for disobedience - will inevitably occur. No soul can escape divine decree, emphasizing the importance of adhering to authentic revelation.
