Musnad Abu Ya'la al-Mawsili 136:3

Husayn ibn al-Aswad narrated to us, Abu Usamah narrated to us, Umar ibn Hamzah narrated to us, Nafi’ (meaning ibn Malik) narrated to me, from Anas ibn Malik, who said: The Messenger of Allah (ﷺ) said: "‘There is no god but Allah’ prevents the servant from the wrath of Allah, as long as they do not prefer the transaction of their worldly life over their religion. If they do that, and then say ‘There is no god but Allah,’ Allah says: ‘You have lied.’"
