This work is a translation of Shaikh Abdul Aziz bin Baz’s book ‘Ad-Duroos Al-Muhimmah li-Ammatil-Ummah.’ It contains concise lessons that explain the fundamental teachings of Islam. This book covers a wide range of basic information such as the meaning of Tawhid (Islamic monotheism), the categories and implications of Shirk (polytheism), the regulations of prayer, and Islamic morals and manners. As the title implies, these are truly essential lessons for everyone who is concerned with the correctness of his Islamic beliefs and acts of worship.

The Prophet said: “Whoever performed a good sunnah in Islam will have the reward of it and the reward of those who perform it after him.” (Narrated by Imam Muslim) and he said: “Pray as you have seen me praying.” (Narrated by Bukhari and Ahmad)

It is with such ahaadeeth in mind that Sameh Strauch, the author, has attempted to bring to the attention of the English-speaking Muslims some of the sunan relating to prayer which, regrettably, are rarely or never performed in our time, in the hope that it will inspire the readers to revive them.
