As salaam aleykum Is Ileau us Sunan a reliable book for Hanafi sources, i heard this book is praised by many scholars is this true? Was salaam

All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad is His slave and Messenger. We ask Allaah to exalt his mention as well as that of his family and all his companions.

I'laa' As-Sunan is one of the immense books which is authored on the Hanafi School of jurisprudence Fiqh. This book is composed of eighteen volumes, and was authored by Shaykh Thafar Ahmad At-Tahaanawi . It came as a response to the people who say that the Hanafi School of jurisprudence lacks evidence supporting their opinions.

One of these volumes was an introduction to the science of Hadeeth (Prophetic narrations) and another volume is an introduction to the reasons of differences (of opinions) between the scholars . The remaining volumes were about the branches of the Hanafi School of jurisprudence supported by evidence.

Therefore, this book is one of the main references in the Hanafi School of jurisprudence.

Allaah Knows best.
