Answer
(Fatwa: 936/936=J)
Condoms are used for three objectives: for income factor; the income is less and children are more, so how to feed them? (2) for enjoyment; to delay childbirth in order to avoid interruption in enjoying the wife (3) for health of the child or wife; delivery after one another is hurdle in nourishing the child or the wife is unable to bear the difficulties of another delivery. So, using the condom or any contraceptive for first reason is disallowed, haram and a sign of weakness in Belief; since it means that this person considers himself a sustainer whereas Sustainer is only Allah: ان اللہ ھو الرزاق ذو القوۃ المتین (القرآن) while using condom for second reason is makrooh (undesirable) and against the objective of nikah. And, for third reason it is allowed; there is no wrong in doing so according to Shariah.
