as is evident from his own wording (1). And Allah knows best.

2 – Establishing its attribution to the author:
There is no doubt that this book is authentically ascribed to Ibn al-Qayyim, for several reasons:
1 – The author himself mentions it in Iʿlām al-Muwaqqiʿīn, as noted above.
2 – The manuscript copies explicitly attribute it to him, as already indicated.
3 – It is listed by some of his biographers—such as al-Ṣafadī and others—as previously mentioned.
4 – A number of scholars have cited the book, including Ibn al-Nahhās, al-Sakhāwī, and al-Saffārīnī, as stated earlier.
5 – The author quotes within it from his two teachers: Abū al-ʿAbbās Ibn Taymiyya and Abū al-Ḥajjāj al-Mizzī (2).
6 – He also refers to those who objected to him (3) on the question of not requiring a third participant (muḥallil) in horse-racing or archery wagers—an issue that in fact led to the trial he faced for issuing a legal opinion on the matter.
