He also produced a separate, slim volume on the hadith of Gabriel that defines faith and Islam (1)—apart from the previously cited Book of Faith—in a concise manuscript (2).

He commented many times on the hadith, “The adulterer is not a believer while he is committing adultery” (3);

the hadith, “The Qur’an was revealed in seven modes of recitation” (4), which he explained on more than one occasion;

the hadith concerning the Divine Descent, which he expounded several times (5);

and the hadith of the Friends of Allah that al-Bukhari alone transmits (6): “Whoever shows enmity to a friend of Mine, I declare war on him.” He clarified this tradition repeatedly—sometimes addressing the entire text, at other times focusing on the ‘hesitation’ mentioned therein.

He likewise wrote on the hadith of Ḥakīm ibn Ḥizām, “I entered Islam on the basis of whatever good I had done before” (7), and on the hadith related by Ibn Masʿūd about the removal of anxiety.
