Question: How does a person’s limbs fast?
Sheikh ‘Abdul ‘Azeez bin ‘Abdillaah bin Baaz, may Allaah have mercy upon him, answers:
“The limbs fast by staying away from what Allaah has made unlawful from sins, this is how they fast. So he shouldn’t touch with his hands or mouth what Allaah has made unlawful for him to touch, he shouldn’t look with his eyes at what Allaah has made unlawful for him to look at, he shouldn’t walk towards what Allaah has made unlawful for him to walk towards and like this. Refraining them and abstaining from what Allaah has made unlawful.
When the Mu’min (believer) fasts, his limbs also fast.
His tongue fasts from lying, his eyes fast from looking at the prohibited things, his hand(s) fast from the forbidden touch and his legs from walking to the forbidden.”
