Musannaf Ibn Abi Shayba 33:736

Abu Khalid al-Ahmar narrated to us, from Ibn ‘Ajlan, from ‘Awn, who said: The one who remembers [Allah] among the heedless is like the one who fights among those who are fleeing. And the heedless one among those who remember [Allah] is like the one who flees among those who are fighting.
