Does A Transparent Garment Cover the 'Awrah
Question:
Does a transparent garment correctly cover one's 'Awrah or not? And if a Muslim prays in such a garment, is his prayer correct?
Answer:
If the garment does not conceal the skin because it is transparent or thin as described in the question, a man's, prayer is not correct, unless he is wearing something else underneath that properly covers what is between the knee and the navel. The woman's prayer in this garment is also not correct, unless in her case, she is wearing something underneath that covers the whole body properly. It is not sufficient for a man to simply wear short pants underneath. Also, when praying in such a garment, he must wear something that covers one or both of his shoulders. This is because the Prophet (sallAllaahu `alayhi wa sallam) said,
"Let not one of you pray in a single garment, with nothing on his shoulders." (Al-Bukhari no. 359 and Muslim no. 516)
Its authenticity is agreed upon.
