I wanted ask that what should I do about this matter , I saw in one of your videos that pointing feet towards qibla is not a sin but when I told my family about this they got really furious and started telling me that one of my aunt got really sick because their bed was pointed towards the qibla and that she recovered as soon as she changed her bed’s direction.
