Maliks Muwatta Book 3, Hadith Number 25.
Section : The Recitation of Qur’an in the Maghrib and Isha Prayers.
Yahya related to me from Malik from Ibn Shihab from Ubaydullah ibn Abdullah ibn Utba ibn Masud from Abdullah ibn Abbas that Umm al-Fadl bint al-Harith heard him reciting al Mursalat (sura 77) and she said to him, “My son, you have reminded me by reciting this sura that it was what I last heard the Messenger of Allah, may Allah bless him and grant him peace, recite in the maghrib prayer.”
