In one of the tapes, one of the brothers asked you about praying in trousers while his 'awrah (the part of the body that must be covered) was exposed, and you said: If he knows that and continues, his prayer is invalid.

The questioner : I heard you on a cassette tape: one of the brothers asked you about praying in trousers, specifically regarding the issue of dividing the 'awrah (the part of the body that must be covered) and its depiction. You said in this tape: If he knows that and continues, his prayer is invalid. However, in a later session, I heard you say something else, namely that it is disliked with a prohibition-level dislike and that you are cautious about declaring his prayer invalid.

The Shaykh : Yes, but the second tape does not contain the detail that you heard in the first tape.

The questioner : Please benefit us, may Allah reward you.

The Shaykh : I am finished now; my family is about to come.

The questioner: May Allah reward you with all good.

The Shaykh : And beware of that.
