We were with the Prophet (ﷺ) when he said (to two men), "I shall judge between you according to Allah's Book (Laws)."
Sahih al-Bukhari Book 96, Hadith 11
← Previous Hadith 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).

Sahih al-Bukhari Book 96, Hadith 10 Next Hadith → Allah's Messenger (ﷺ) said, "All my followers will enter Paradise except those who refuse." They said, "O Allah's Messenger (ﷺ)! Who will refuse?" He said, "Whoever obeys me will enter Paradise, and whoever disobeys me is the one who refuses (to enter it)."
