Book 0: The book of the sunnah
Chapter 1: Following the sunnah of the Messenger of Allāh (peace and blessings of Allāh be upon him)

Ḥadīth [3]: It was narrated that Abī Hurayrah (may Allāh be pleased with him) said: The Messenger of Allāh (peace and blessings of Allāh be upon him) said: “Whoever obeys me, obeys Allāh; and whoever disobeys me, disobeys Allāh.”

• Ṣaḥīḥ al-Bukhārī (2957 & 7137)

Grade:

• Ṣaḥīḥ by Ḥāfiẓ Zubayr ‘Alī Za’ī (Sunan ibn Mājah) [1]
• Ṣaḥīḥ by Shaykh al-Albānī (Sunan ibn Mājah)
• Ṣaḥīḥ isnād by Shaykh Shu’ayb al-Arna’ūṭ (Sunan ibn Mājah)

[1] Ḥāfiẓ Zubayr ‘Alī Za’ī had not mentioned any grade in his research, but he had mentioned the sources from Ṣaḥīḥ Muslim and Ṣaḥīḥ al-Bukhārī; so based on that, we have attributed to him grading the ḥadīth as ṣaḥīḥ. And Allāh knows best.
