Hadith.38 - Imam Ali ibn Abi Talib (as) used to say:
"There is no servant (of Allah (swt)) except that there is an angel appointed to turn his head to look at his excrement, and then the angel says to him:
'O’ child of Adam, this is your provision, so consider from where you took it and to what it has turned.'
It is appropriate for the servant at that moment to say:
Allāhumma urzuqnī al-ḥalāla wa jannibnī al-ḥarāma
‘O’ Allah (swt), grant me lawful provision and keep me away from the unlawful.'"
