There are two main sources that guides a Muslim towards a holistic understanding of Islam: The Holy Qur’an and the collections of the recorded words, actions and sanctions of the Prophet’s ﷺ which make up the Sunnah and which are normally referred to as Hadith. Imam Nawawi’s 40 hadith is considered as the most foundational hadiths of the Prophet, Blessings and Peace be Upon Him. A deeper understanding, appreciation and application of these hadiths can only nurture your faith, deepen your religious understanding and increase your love for the Beloved Prophet, Blessings and Peace be Upon Him, which will ultimately lead to the strengthening of your deen Insha'Allah.
