The book deals with the concept of Loving for the sake of Allah and hating for the sake of Allah. It was originally submitted for a Masters Degree at the Department of Aqeedah Umm al Qorah University in Makkah. The subject matter of this work is of paramount importance and utmost interest for two major reasons: Firstly, it is concerned with one of Islam’s main foundations, namely the qualities of al-wala’ wa’1-bara’, which are two major prerequisites of true faith: al-wala’ is a manifestation of sincere love for Allah, His prophets and the believers; al-bara’, on the other hand, is an expression of enmity and hatred towards falsehood and its adherents. Both are evidence of iman. Secondly, it has been written at a very crucial time: everything has become so mixed up that some Muslims are no longer aware of those qualities which distinguish the believers from the non-believers; their faith has become so weak that they have adopted patterns of behaviour that are absolutely repugnant to a sincere believer; they have taken the disbelievers as their friends, while displaying enmity towards many of the believers by disparaging their character and degrading them.
