Happiness is a feeling that resides in the heart. It is characterized by peace of mind, tranquility, a sense of well-being, and a relaxed disposition. It comes as a result of proper behavior, both inward and outward, and is inspired by strong faith. This is attested to by the Qur’ân and Sunnah. Happy marriages are fundamental to a stable family and for personal well being. This book is specifically written for men so that inshallah they can have successful marriages.

A very important series begins on the list today, concerned with the subject of al-Jannah and an-Naar - the Paradise and the Hell-Fire. One of these two will be the end destination; moreover the eternal abode, for each and every one of us. Therefore it is crucial for us to reflect on what Allah has prepared for mankind - for those who are obedient and recognise His favours, and for those who reject His sins and rebel against Him.
