In the name of الله, the most gracious, the ever merciful . All praise is due to الله. And may الله send his salutations and mercy and blessings on his messenger Muhammad. To proceed:

Know! May الله have mercy on you, that it’s Waajib upon you to learn your religion! Now this in of itself is a series of lectures and for more if Romario read usool al thalatha with its sharh, but to break it down, you need to know how to pray, as if you pray without knowledge this is action without knowledge and this is indeed a great danger and shaykh Al fawzaan said regarding action without knowledge, it’s something that will harm you and not benefit (see sharh usool al thaltha) this book, may الله have mercy on the author, the explainer and the translator and who ever reads it and act upon that knowledge, is a tremendous book. It’s short but its benefit is great. It shows you the arkaan and waajibaat and the shuroot of the prayer. It explains what certain supplication means and what surah al fatihah means and what you say in the tashadud, what it means. It’s of high benefit بارك الله فيك. Highly recommend this book for
the one who fears الله and the last day

may His سبحانه وتعالى Salât and Salâm be upon our Prophet Muhammad and on his followers and Companions altogether.
