this book originally was written by sheikh taqiyudin an nabhani,but because of security reason,he gave to his friend ustadz ali raghib as an author and he want to take the responsibility of this book content.
when you read this book yoou can feel the way the taqiyudin writes book,he quote the daleel directly from quran and hadits,you won't find many imaam opinion in this book,but you can feel the same way the imaam of ushul made up their opinion.al ahkamu sholat not has any different than any other imaam mazhab.
