Thinking only in terms of this Dunya, there seems to be very few things I could not do without. Those being food, water, shelter and a place to sleep. The food can be anything halal and in sufficient amount to keep me alive. The water need not be pure only free from disease pathogens and toxins, the shelter need only be warm and dry. the place to sleep need only be a place I can stretch my body.
Anything else would be my wants and desires, not needs for me to survive this dunya.
So few things in this life have any real value. The secret to life is not to gain all you need to be comfortable, the secret is to learn how little you actually need to live..
