I understand that Marriage is important, but I've also heard that it is allowed for a single woman to stay single/bachelor forever, under the condition that she will not commit any sin (adultary). Keeping this in mind,I have also heard that to intentionally choose to be single for life, a legitimate reason for doing so, is required. What would a legitimate reason be?
My sister has decided she doesn't want to get married, as since she was born till now (her mid twenties), she has witnessed only the (extreme!) negatives of couple/married life amongst families. Is her traumatic experience enough to make this decision? Also, our family is accepting of this decision if it makes her happy, but we want to know what Islam says before making any thoughts/decisions permanent.
Please could you provide an explanatory answer with islamic evidence? ~ Jazakalla
