If there is a reason for prostration, but he forgot and did not remember until after he had said the closing salam, and perhaps some of the worshippers had already dispersed, and then he remembered afterwards?

The questioner : If there is a reason for prostration, but he forgot and did not remember until after he had said the closing salam, and perhaps some of the worshippers had already dispersed, and then he remembered afterwards?

The Shaykh : Yes, he prostrates if he remembers.

The questioner : Yes.

The Shaykh : He prostrates if he remembers, except that some of the scholars say: if the interval is long, the prostration is dropped from him at that time, because it is not built upon the prayer due to the long interval between it and the prayer. And some of the scholars said that whenever he remembers, he prostrates for forgetfulness.

The questioner : At what time?

The Shaykh : Allah knows best what is correct. I have no preference in this issue.

The questioner : Yes, and the prayer is valid.

The Shaykh : And perhaps I would prefer that if the interval is long, he does not prostrate.

The questioner : Yes.

The Shaykh : Yes.

The questioner : And if he dispersed without prostrating, is his prayer valid?

The Shaykh : Yes, the one who dispersed, those who left and did not prostrate, their prayer is valid.

The questioner : Valid?

The Shaykh : Yes.

The questioner : This one has a final question, in which he says.
