aṣ-Ṣaḥīḥayn (The Two Ṣaḥīḥs) are the two great books of Ḥadīth: Ṣaḥīḥ al-Bukhārī, compiled by Muḥammad ibn Ismāʿīl al-Bukhārī, & Ṣaḥīḥ Muslim, compiled by Muslim ibn al-Ḥajjāj. Both are considered not only the most authentic books within the field of Ḥadīth, but also the most authentic books after the Book of Allāh. One may question, “Is every Ḥadīth in Ṣaḥīḥ al-Bukhārī & Ṣaḥīḥ Muslim completely authentic?” — Shaykh ʿAbd al-ʿAzīz ibn ʿAbdullāh ibn Bāz رحمه الله (d. 1420 AH/1999 CE) explains:
“There aren’t any weak Aḥādīth in aṣ-Ṣaḥīḥayn. All of the Aḥādīth in these two books are Ṣaḥīḥ, and have been accepted by the Ummah as being authentic and strong. Although a (very) small amount of the Aḥādīth may be considered as Ḥasan (fair), but overall, they are authentic. The Aḥādīth of Imām al-Bukhārī and Imām Muslim are all to be accepted and considered as authentic.
The people of knowledge have accepted them (as authentic), but there is one Ḥadīth which some scholars don’t accept in Ṣaḥīḥ Muslim which they say is a mistake. It is the Ḥadīth of Abū Hurayrah that The Messenger of Allāh ﷺ said: ‘Allāh created the clay on Saturday’ [Ṣaḥīḥ Muslim #2789], and then the Ḥadīth mentions what was created on the rest of the days and Friday, so this Ḥadīth mentions that the creation happened in seven days. Imām al-Bukhārī and others have mentioned that this is a mistake and that it is actually from the speech of Kaʿb al-Aḥbār but some of the narrators got confused and said that it is the speech of The Messenger of Allāh ﷺ narrated by Abū Hurayrah. This is the correct stance, that this Ḥadīth is a mistake, as it was attributed to Prophet Muḥammad ﷺ.
Allāh mentions in the Qurʾān that He created the heavens and the earth in six days (not seven). This Ḥadīth narrated from Abū Hurayrah is a mistake and it is actually the speech of Kaʿb al-Aḥbār.“
May Allāh have abundant mercy upon Shaykh ʿAbd al-ʿAzīz ibn ʿAbdullāh ibn Bāz & reward him for his great contributions to the religion of Islām.
All praise is due to Allāh, may His peace & blessings be upon our final Prophet Muḥammad, his family, his companions, & all those who follow him in guidance.
