Muslim (2/142) also recorded it through al-Muthannā, from Qatādah, from him.

Saʿīd—namely Ibn Abī ʿArūbah—likewise transmitted it from Qatādah with the wording, “Whoever forgets a prayer or sleeps through it …,” the remainder being identical.

Al-Dārimī (280) narrated it, Saʿīd informing us in these words: “Its expiation is that he perform it when he remembers.”

This very wording was likewise reported by Shuʿbah from Qatādah and included by Aḥmad (3/282).

Ḥajjāj al-Aḥwal related it in al-Nasa’i (100), Ibn Mājah (235), and Aḥmad (267), and Hishām did the same in Aḥmad (216), all from Qatādah on the authority of Anas. Anas asked the Messenger of Allah ﷺ about a man who sleeps through the prayer or is inattentive to it, and he replied, “Let him perform it when he remembers.”

The narration is also found in al-Bukhārī and Muslim, in Abū Dāwūd (73), al-Ṭaḥāwī, al-Bayhaqī (2/218), and Aḥmad (269), through the route of Hammām from Qatādah, in the wording: “Whoever forgets a prayer, let him pray it when he remembers; there is no expiation for it except that.” Qatādah then recited, “And establish the prayer to remember Me” (Q 20:14).

Abū ʿAwānah likewise transmitted it from Qatādah in abridged form, omitting the phrase “there is no expiation for it….” Muslim, al-Nasa’i (100), al-Tirmidhī (335–336), Ibn Mājah, al-Ṭaḥāwī, and al-Bayhaqī also recorded it through various chains from him.

Finally, Qatādah explicitly stated that he had heard it directly from Anas in a narration preserved by al-Bukhārī and Aḥmad.
