The questioner : Regarding praying in tight trousers, the observation is that most of the youth in the mosques, except for a very few, pray in trousers. They may be tight, form-fitting, and so on...

The Shaykh : And every affliction is in it

The questioner : And every affliction is in it. We see some of the youth, meaning, the young man may be handsome in appearance, and if you want to advise him, you want to tell so-and-so, and you may be accused of having given bad advice, so what is the ruling on praying in trousers?

The Shaykh : The ruling on praying in trousers is that it is lawful, and the prayer is valid, if Allah wills.

The questioner : Even if it shows

The Shaykh : his buttocks

The questioner : No, I mean, if his back is exposed below the navel

The Shaykh : If it is under the visible part, meaning it covers what is below the navel, then this is not an awrah (part of the body that must be covered) if the visible part is what is above the navel. But if it is below the navel, it is not valid.

The questioner : And what is the ruling on the prayer?

The Shaykh : It is invalid

The questioner : And he is ordered to repeat it
