«الحلال ما أحل الله في كتابه والحرام ما حرم الله في كتابه وما سكت عنه فهو مما عفا عنه»
The Prophet (peace and blessings be upon him) said:
"The lawful is what Allah has made lawful in His Book, and the unlawful is what Allah has made unlawful in His Book, and whatever He remained silent about is among the things He has pardoned."
