Reference: Fataawa al-Lajnah ad-Daa.imah lil-Buhooth al-‘Ilmiyyah wal-Iftaa., – Volume 12, Page 361, Question 2 of Fatwa No.9354
Question: Is it permissible for me to go on leisure outings with my husband and my children to places like [public] parks, museums and exhibitions, without [free] mixing or missing the [obligatory] prayers, with the knowledge that by necessity I will uncover my face in these places. And [also] is it permissible for us to accompany our children to beaches for swimming, knowing the immorality [which occurs] in these places and the prevalence of nakedness and permissiveness there?
And how should we respond to those who say: “We are forbidden to enjoy that which Allaah has created”, [knowing] that a person is unable to lower their gaze to avoid seeing things that are forbidden by Allaah, because they are so widespread in these places?
Response: It is not permissible to go to places in which reprehensible acts (munkaraat) are prevalent, [particularly since] there is sufficient enjoyment in the things which Allaah has permitted for us, and we have no need of that which He (Subhaanahu wa Ta’aala) has forbidden for us.
And with Allaah lies all success and may Allaah send prayers and salutations upon our Prophet ﷺ and his family and his companions.
