This book deals with the epidemic of smoking, which enslaves many of today’s Muslims, and which is aggravated by that most victims belittle its dangers and deny its prohibition.

This book includes a discussions of intoxicants, establishing the prohibition of various practices associated with them, as well as penalties (in both lives) for those who partake in them.

This book also includes a discussion of narcotics, with an overview of marijuana and qaat (or khat). Based on their established effects and harms, we conclude that narcotics are strongly prohibited, except in very limited medical settings.

This book, we hope, will provide many Muslims with guidance toward a healthier, cleaner and worthies Islamic personality. My Allah grant us guidance and facilitation.

This book offers a detailed presentation of the theory of Muslim law (usul al-figh). Often regarded as the most sophisticated of the traditional Islamic disciplines, Muslim jurisprudence is concerned with the way in which the rituals and laws of religion are derived from the Qur’an and the Sunna – the precedent of the Prophet. Revelation, which is given to man to restore unity and help him achieve a just and devout order in society as well as in the soul, must be interpreted so as to render it practicable in every culture, while not betraying its spirit and immutable provisions. To achieve this, additional sources of legal authority are recognized, including consensus (ijma), analogical deduction (qiyas), public interest (maslaha) and local customary precedent (urf). In employing these, the jurist guards the five principles which it is the purpose of Islamic law to uphold, namely, the right to life, sound mind, property, lineage and religion.
