Things which it is disgraceful to discuss; matters which would distress certain people; and such reports as I have been told are not to be accepted as trustworthy – all these things have I omitted. [Ibn Hashim, p. 691.]
We can discern three strata of the Sunni ḥadīth canon. The perennial core has been the Ṣaḥīḥayn. Beyond these two foundational classics, some fourth-/tenth-century scholars refer to a four-book selection that adds the two Sunans of Abū Dāwūd (d. 275/889) and al-Nāsaʾī (d. 303/915). The Five Book canon, which is first noted in the sixth/twelfth century, incorporates the Jāmiʿ of al-Tirmidhī (d. 279/892). Finally, the Six Book canon, which hails from the same period, adds either the Sunan of Ibn Mājah (d. 273/887), the Sunan of al-Dāraquṭnī (d. 385/995) or the Muwaṭṭaʾ of Mālik b. Anas (d. 179/796). Later ḥadīth compendia often included other collections as well. None of these books, however, has enjoyed the esteem of al-Bukhārīʼs and Muslimʼs works.
