In this book, Shaykh ul-Islam Ahmad Ibn Taymiyah discusses the Islamic answers to the basic human questions in depth. He explains in detail the purpose of our existence, which is to be true slaves of Allah, making Him the focus of our love and attaining happiness and fulfilment by making Him our goal. Following a similar theme to 'Patience and Gratitude', this book also offers practical advice for our everyday lives taken from the Qur'an and Sunnah. It shows us how to purify our hearts, since a heart that is not pure cannot find tranquillity.
