Question
Must I repeat the prayers I performed wearing a see-through scarf?
Answer
In the Name of Allah, the Most Merciful and Compassionate
If the scarf is so thin that the skin color of the ears can be easily discerned, the prayer is invalid. This is because exposing one-fourth of any limbs that are incumbent to cover (in this case, the ear) invalidates the prayer. [Ibn Abidin, Radd al-Muhtar]
Rules of Exposing Nakedness (Awra)
The Sacred Law outlines for us what is considered nakedness and what is not. A woman must cover her entire body in the prayer except for her face, hands, and feet. [Ibid.]
The limits of the face allowed to be exposed in prayer are the same as those in the wudu. Thus, the ears are not considered from the face and must be covered. It must cover the area such that the area cannot be seen. [Ibid.]
If the one-fourth was exposed when commencing the prayer, the prayer is not considered to have begun. [Ibid.]
If the exposing occurred during the prayer, unintentionally, and lasted for the amount of time it takes to say SubhanAllah thrice, the prayer is invalid. [Ibid.]
If intentional, the prayer is invalid, regardless of the amount of time. [Ibid.]
Making Up Prayers
Only makeup prayers that you are certain your ears were exposed (either entirely or such that the skin color can be seen through the scarf). If you doubt whether or not the skin could have been seen, do not repeat that prayer. Lastly, estimate the number of prayers you are certain were invalid and make them up, little by little, every day.
Hope this helps
Allah knows best
