“Truthful, with some weakness.”

Abu Mu‘awiyah al-Ḍarīr—who is trustworthy—also narrated it through both of them in the Musnad of Ibn Rāhwayh (3/933–934), but without mentioning Masrūq. Part of it is found in Ṣaḥīḥ al-Bukhārī (3935), Abu ‘Awanah (2/28), and Ibn Rāhwayh (2/107/31), through Ma‘mar, from al-Zuhrī, from ‘Urwah, from ‘Ā’ishah, in a shortened form: “The prayer was prescribed as two rak‘ahs; then the Prophet, peace and blessings be upon him, emigrated, and it was prescribed as four, while the travel prayer was left as it had originally been.” It was reported by al-Bukhārī and Muslim without mention of the emigration, and its sourcing has preceded in Ṣaḥīḥ Abī Dāwūd (1082).

As for the supporting report, al-Ḥāfiẓ Ibn Ḥajar recorded in al-Maṭālib al-‘Āliyah al-Musnadah (fol. 25/2): “Isḥāq (1): I said to Abū Usāmah: ‘Did Sa‘d ibn Sa‘īd al-Anṣārī narrate to you that he heard al-Sā’ib ibn Yazīd say: The prayer—Dhuhr and ‘Aṣr—was prescribed as two rak‘ahs each. They would then pray two rak‘ahs after Dhuhr and two rak‘ahs after ‘Aṣr. Then Dhuhr and ‘Aṣr were prescribed for them as four rak‘ahs, so they abandoned that when it was prescribed for them; while the travel prayer remained [two rak‘ahs], and the resident prayer was four?’ He confirmed it and said: ‘Yes.’”

Al-Ḥāfiẓ said: “This is a good hadith.”
