Does a man's prayer become invalid if he prays in trousers that describe or define the size of the 'awrah?

Allah Almighty commanded the taking of adornment at every mosque, and scholars considered the minimum extent of taking adornment to be covering the 'awrah (intimate parts), which is a condition for the validity of prayer. The implication of this is that what is obligatory is to cover the 'awrah, and prayer is valid no matter how the covering is achieved, even if the garment is tight and defines the 'awrah. This is what the four schools of jurisprudence have stipulated: 1. Hanafi School: The clinging of the garment to the body and its shaping does not harm (the prayer's validity), for as long as it covers the color of the skin, the prayer is valid. 2. Shafi'i School: Prayer is valid in a garment that covers the color (of the skin) even if it describes the size of the body. 3. Maliki School: Praying in a garment that describes or defines the 'awrah is disliked (makrooh), but not forbidden. Re-performing the prayer within the prescribed time is recommended. 4. Hanbali School: It is not considered (a condition) that the garment should not describe the size of the limb, because it is impossible to guard against that.

Tight clothing should not be worn or prayed in, as it contradicts the desired adornment. However, praying in it is valid, though one incurs sin by wearing it, especially for women, due to the temptation it causes and because it may be an interpretation of the Prophet's (peace be upon him) saying: "Women who are dressed yet naked."
