Knowledge and understanding of the ‘deen’ (religion) here stands for the understanding of the Qur'an and the Hadith, religious injunctions, and knowledge of the lawful and the unlawful. This narration highlights the excellence of knowledge and the fact that it is a sign of Allah's Help to the person who possesses it and acts upon it.
