Fast during Ramadan does not stand for only abstaining from eating and drinking. Rather, it also entails that all the body organs fast, i.e., abstain from all things prohibited by Allah. Thus, a tongue should fast and abstain from backbiting, gossip, and lying. Eyes should also fast and refrain from looking at that which Allah prohibited (Part No. 9; Page No. 158) to look at, and ears should fast and thus refrain from listening to that which Allah prohibited to listen to. In this regard, Allah (Exalted be He) said:
Tell the believing men to lower their gaze (from looking at forbidden things), and protect their private parts (from illegal sexual acts). That is purer for them. Verily, Allâh is All-Aware of what they do.
In fact, giving free rein to one’s gaze is a reason for inciting lust and consequently committing sins. Therefore, we advise you to fear Allah, to lower your gaze, and not to look at non-Mahram (not a spouse or an unmarriageable relative) women.As for looking at that woman and then
having foreplay with your wife which led to ejaculation during the daytime of Ramadan, you said you have made up for that day, which is the only obligation plus repenting to Allah. However, you are not duty-bound to any Kaffarah as it is entailed only by intercourse.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
