Musannaf Ibn Abi Shayba 3:3660

Abdah narrated to us, from Hisham ibn Urwah, from Abd al-Wahhab ibn Yahya, from Abbad ibn Hamzah: He said: I entered upon Asma while she was reciting, "So Allah conferred favor upon us and protected us from the punishment of the Scorching Fire." He said: So I stood by her, and she began to seek refuge and supplicate. Abbad said: Then I went to the market and fulfilled my need. Then I returned, and she was still in it, seeking refuge and supplicating.
