Is it permissible for a person to pray a voluntary prayer if there is enough time remaining before the iqamah for one rak'ah?

The questioner:
The questioner: If there is enough time remaining before the iqamah to perform one rak'ah of a voluntary prayer, is it permissible to complete that voluntary prayer?

The Shaykh:
Until when?

The questioner:
He says: If there is enough time remaining before the iqamah to perform the second rak'ah of a voluntary prayer, is it permissible to complete that voluntary prayer?

The Shaykh:
If he is able to finish the voluntary prayer before the prayer is called to begin, yes, he prays. But if there is only a little time left before the iqamah, and he cannot complete the rawatib or the voluntary prayer, or cannot even start it if the iqamah is imminent, then he does not start the voluntary prayer. But if there is time between him and the iqamah in which he can complete the voluntary prayer, then he prays a voluntary prayer; that is good. Yes.
