The ruling on praying four rak'ahs in the night prayer with a single taslim

Question:
He says: In the night prayer, when I pray four rak'ahs with a single taslim, it is easier for me. He asks: Is this permissible?

Answer:
Four rak'ahs with a single taslim; this contradicts the saying of the Messenger (peace and blessings be upon him) . However, it is permissible to recite three rak'ahs of the witr with a single taslim, or five, or seven, or nine with a single taslim; there is nothing wrong with that. Or you may sit at the end, recite the first tashahhud, then stand up and perform the witr, or you may say the taslim; there is nothing wrong with that. The matter is broad in this regard, and praise be to Allah. Yes.
