A test for when you are unsure
One sentence for anything you cannot decide about.
دَعْ مَا يَرِيبُكَ إِلَى مَا لاَ يَرِيبُكَ فَإِنَّ الصِّدْقَ طُمَأْنِينَةٌ وَإِنَّ الْكَذِبَ رِيبَةٌ
Daʿ mā yarībuka ilā mā lā yarībuk.
“Leave what makes you doubt for what does not make you doubt.”
The full narration
Al-Hasan bin 'Ali said:"I remember that the Messenger of Allah (s.a.w) said: 'Leave what makes you in doubt for what does not make you in doubt. The truth brings tranquility while falsehood sows doubt.'" Another chain reports a similar narration
