He also produced an exceptionally large body of writings (1) on individual hadiths and their commentaries: some of it was put into fair copy and some remains in draft, and had it all been finalized it would have filled many volumes. He extracted a substantial portion of the Musnad of Imam Ahmad and other collections, arranging the material under the headings of jurisprudence. He prepared an abridgment of al-Kalim al-Tayyib (Wholesome Words), in which he gathered the supplications recited at the two ends of the day and other invocations (2).

He composed commentaries on the hadith of Abu Dharr that begins, “O My servants, I have forbidden injustice to Myself” (3); on the hadith, “Actions are judged by intentions” (4); on the hadith, “Islam began as something strange” (5); on the hadith, “A Muslim does not inherit from a non-Muslim” (6); and on the hadith containing the supplication the Prophet—peace and blessings be upon him—taught to Abu Bakr al-Siddiq, may Allah be pleased with him: “O Allah, I have greatly wronged myself…” (7).
