Yahya related to me from Malik that he heard that the Messenger of Allah ﷺ said, "I have left two matters with you. As long as you hold to them, you will not go the wrong way. They are the Book of Allah and the Sunna of His Prophet."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ تَرَكْتُ فِيكُمْ أَمْرَيْنِ لَنْ تَضِلُّوا مَا تَمَسَّكْتُمْ بِهِمَا كِتَابَ اللَّهِ وَسُنَّةَ نَبِيِّهِ
