فَمَنِ اضْطُرَّ فِي مَخْمَصَةٍ
But whoever is compelled by severe hunger or necessity.
This Qur’anic phrase (al-Ma’idah 5:3) indicates idtirar, a genuine emergency threatening survival. Under such circumstances, a restricted concession may apply to items ordinarily forbidden as food.
Necessity here does not simply mean preference, convenience, or appetite. Where ordinary lawful means suffice, merely wanting a prohibited substance does not create the required emergency.
