If one vows to pray twenty rak'ahs, does he pray them with a single taslim, or does he say taslim after every two rak'ahs?

Question:
He says: Honorable Shaykh, may Allah grant you success, if one vows to pray twenty rak'ahs, does he pray them with a single taslim, or does he say taslim after every two rak'ahs?

Answer:
The night prayer is prayed in pairs of two, and in a narration, the prayer of the night and the day is prayed in pairs of two, so one says taslim after every two rak'ahs. This is the best, except for the witr. If he wants to pray five, seven, nine, or eleven rak'ahs in a row, he prays them and sits before the last one. He sits and recites the tashahhud but does not say taslim, then he stands up and prays the witr. This is permissible, and it is narrated from the Prophet (peace and blessings be upon him) and that he prays the witr with one rak'ah. This is the best. Yes.
