The source of all evil is the deviation from the truth and its straight path. The goodness of all matters is the following of truth and adherence to its right way. Truth is the fixed state in which Allah has created every creature in a particular way and managed its affair in a certain manner. Allah is Perfect and exempt from any deficiency or error. This book aims to elucidate the pillars of Imaan (basis of belief, faith) and the characteristics of Kufr (disbelief) and its causes.

An summarised text detailing the rules governing the Criticism of Hadeeth. From its introduction -'A hadith (pl. ahadith) is composed of two parts: the matn (text) and the isnad (chain of reporters). A text may seem to be logical and reasonable but it needs an authentic isnad with reliable reporters to be acceptable; 'Abdullah b. al-Mubarak (d. 181 AH) is reported to have said, "The isnad is part of the religion: had it not been for the isnad, whoever wished to would have said whatever he liked." During the lifetime of the Prophet (SAS) and after his death, his Companions (Sahabah) used to refer to him when quoting his sayings. The Successors (Tabi'un) followed suit; some of them used to quote the Prophet (SAS) through the Companions while others would omit the intermediate authority - such a hadith was known as mursal (loose). It was found that the missing link between the Successor and the Prophet (SAS) might be one person, i.e. a Companion, or two persons, the extra person being an older Successor who heard the hadith from the Companion.'
