Further to my earlier post on the commentaries of the Sahihain, this is a synopsis of an article by Shaykh Dr. Muhammad ibn Abd al-Karim ibn Ubaid (Professor of Hadith Sciences at Jamia Umm al-Qura, Makka) that was published in the Umm al-Qura Journal. The essay was titled: riwaayat wa nusakh al-Jami as-Sahih lil-Imam Abi Abdillah Muhammad ibn Ismail al-Bukhari.
As the title indicates, this essay seeks to list the many variant readings of the Sahih from its author.
It will interest any serious student of the Sahih al-Bukhari.
