Is it obligatory to make up for a day on which one ejaculated with desire after watching (something), without touching the private parts, during a Ramadan day? And is expiation sufficient instead of making up for it, for fear of the matter being exposed to the family?

It is forbidden for a Muslim to look at indecent images due to the corruption they cause to the heart, and he must offer sincere repentance. Scholars differed regarding the invalidation of the fast by ejaculation resulting from looking without touching. The Hanafis and Shafi'is held that it does not invalidate the fast, while the Hanbalis and Malikis disagreed. It is preferable to make up the fast to avoid disagreement. As for concealing making up the fast from the family, they can be led to believe it is a voluntary fast, knowing that shyness that leads to abandoning acts of worship is blameworthy.
