The Messenger of God, may God’s prayers and peace be upon him, said: “Whoever God wants good for, He gives him understanding of religion.” And jurisprudence is the true understanding of the matters of religion, its rulings, and its issues. It is obligatory for a Muslim to learn the matters of his religion and its legal rulings, and agree on them. This book - which is in our hands - deals with all the jurisprudential matters that pertain to a Muslim in his religion and his world, from acts of worship and their rulings, purity and etiquette, transactions, marriage, inheritance, borders and etiquette, as it includes everything a Muslim needs in the affairs of his life and the hereafter. The author of this book has presented his material in a modern, easy and simplified manner, based on brevity and clarification, which is the goal of every Muslim who may find it difficult to understand some matters. Because of the difficulty of its formulation and the complexity of its conventions. The author has resorted to dissolving these difficulties and simplifying the jurisprudential terminology. He has also moved away from the matters that are disputed among the jurists, and adhered to the matters agreed upon, which is something that shows the tolerance and ease of Islam in dealing with issues and rulings. To the opinions of the overindulgent. This book is the result of the author's effort and sweat to show jurisprudence in an easy way that allows every reader to understand the matters of his religion simply, and it is a precious wealth that every Muslim should seek to acquire. To preserve his religion and understand his issues properly without hardship or fatigue.
