Musannaf Ibn Abi Shayba 3:3659

Waki’ narrated to us, he said: Al-A’mash narrated to us, from Abu al-Duha, from Masruq, from ‘Aisha, that she passed by this verse: "So Allah conferred favor upon us and protected us from the punishment of the Scorching Fire." She said: "O Allah, confer favor upon us and protect us from the punishment of the Scorching Fire; indeed, You are the Benign, the Merciful." It was said to Al-A’mash: "In the prayer?" He said: "In the prayer."
