What is Shaykh Ibn Uthaymeen’s opinion on the book al-Mughni in fiqh?

Question : The questioner from Riyadh says: What is your opinion, Honorable Shaykh, on the book al-Mughni, and is it sufficient to refer to it for fiqh issues?

Answer : Our opinion on the book al-Mughni is that it is among the best works written in its field, meaning in the field of fiqh, where the author reviews the opinions of the scholars and mentions the stronger position with the evidence he holds. However, like other books written by humans, and humans err and hit the mark, it may contain some weak matters based on weak reports, and it may contain some weak matters based on an understanding that was not intended in the texts. But in any case, it and al-Majmu' Sharh al-Muhadhdhab are among the best that has been written in this field.
