The Lajnah (Permanent Committee For Scholarly Research And Ifta’) was asked:
What is the ruling on leaving during work due to an emergency without taking permission from the boss?
“It is necessary to ask permission from your boss during work. It is not allowed to leave except with his permission, unless you have an affair which is necessary and your boss is not present. In that case, you inform your colleagues when you are leaving and the reason for leaving so that they can inform your boss”.
Faisal Ibn Abdul Qaadir Ibn Hassan
