On the authority of his father, from the Prophet ﷺ, who said that whenever the Messenger of Allah ﷺ entered the morning, he would say, "We have entered the morning upon the natural disposition of Islam, the word of sincere devotion, the religion of our Prophet Muhammad ﷺ, and the creed of our father Ibrahim, who was upright and submitted to Allah, and was not among the polytheists."In another narration, it adds, "And when he entered the evening, he said the same."
ى، عن أبيه، عن النبي ﷺ أنه قال: كان رسول الله ﷺ له إذا أصبح يقول: أصبحنا على فطرة الإسلام، وكلمة الإخلاص، ودين نبينا محمد ﷺ، وعلى ملة أبينا إبراهيم حنيفا مسلما، وما كان من المشركين. زاد في رواية: وإذا أمسى.
Ahmad (15367, 15363), Darimi (2730), Nasai in Amal al-Yawm wal-Layla (1, 343, 344), and Ibn Sunni (35) all narrated it through various chains from Sufyan (that is, Thawri), from Salama bin Kuhayl, from Abdullah bin Abdul-Rahman bin Abza, from his father, and he mentioned it.This is how most narrators reported it from Thawri, including hafiz imams such as Yahya bin Saeed Qattan and Waki. Waki added in his narration, "and when evening comes."Shuba differed from him, narrating it from Salama bin Kuhayl, from Dhirr (that is, Ibn Abdullah Marhabi), from Saeed bin Abdul-Rahman bin Abza, from his father, and he mentioned it. This was recorded by Ahmad (15364) and Nasai in Amal al-Yawm wal-Layla (3, 345).Thawri has better memory than Shuba, as Shuba himself acknowledged, and a number of hadith critics stated this explicitly. However, there is no reason not to say that Salama bin Kuhayl, who is thiqah and thabit, used to narrate it both ways, so each of Thawri and Shuba reported the version he heard from Salama. And Allah knows best.Its chain is hasan, for Abdullah bin Abdul-Rahman bin Abza is hasan al-hadith. Athram related from Ahmad that he said, "He is hasan al-hadith," and Ibn Hibban mentioned him among the thiqat.
