There is a difference between skepticism and productive thinking.

Adeel Riaz

Al-Hasan ibn Ali reported: The Messenger of Allah, peace and blessings be upon him, said:

دَعْ مَا يَرِيبُكَ إِلَى مَا لَا يَرِيبُكَ فَإِنَّ الصِّدْقَ طُمَأْنِينَةٌ وَإِنَّ الْكَذِبَ رِيبَةٌ

Leave what makes you doubt for what does not make you doubt. Verily, truth brings peace of mind and falsehood sows doubt.
