I would like to ask you 3 questions, I would be grateful if you would answer them, 1st is masturbation allowed for a male who cannot marry or cannot afford to fast, 2nd what is said in Islam about the world wars or a possible 3rd world war,lastly what is said in islam about extra terrestrial planets[such other planets in which we may go and live]

1: It costs more to eat than to abstain from food, so there`s no logic in that - only desires and whispers from shaitaan. When you make sins, ask for forgivenes and repent to Allaah again and again, but don`t try to make it Halaal. Try to leave it, try to control it, and try to fill your life with the greater enjoyments: the acts of obedience to your Lord.
