The book, “Umdatul-Ahkaam”, is compiled by hadeeths only from the Saheehs of Imaam Bukhaaree and Imaam Muslim. The majority of the hadeeths in “Umdatul- Ahkaam” are Muttafaqoon ‘alayh (agreed upon): meaning that they are recorded by both Sheikhs, in their respectable Saheehs. There are very few hadeeths in this book which are only reported by Imaam Bukhaaree or only by Imaam Muslim. Therefore, all the hadeeths of “Umdatul-Ahkaam” are authentic hadeeths.
