Maliks Muwatta Book 3, Hadith Number 26.

Section : The Recitation of Qur’an in the Maghrib and Isha Prayers.

Yahya related to me from Malik from Abu Ubayd, the mawla of Sulayman ibn Abd alMalik, from Ubada ibn Nusayy from Qays ibn al Harith that Abu Abdullah as-Sunabihi said, “I arrived in Madina in the khalifate of Abu Bakr as-Siddiq, and I prayed maghrib behind him. He recited the umm al Qur’an and two suras from the shorter ones of the mufassal in the first two rakas. Then he stood up in the third and I drew so near to him that my clothes were almost touching his clothes. I heard him reciting the umm al-Qur’an and this ayat, ‘Our Lord, do not make our hearts go astray after You have guided us, and give us mercy from Your presence. Surely You are the Giver.'” (Sura 3 ayat 8)
