Is it permissible in the supplication of the qunut of witr to supplicate for the Muslims and to curse the disbelievers?

The questioner : Is it permissible, after the supplication of the qunut in the witr prayer, to supplicate for the Muslims and against the disbelievers?

The Shaykh : If he were to perform qunut in the five daily prayers, and it occurred to him to perform qunut in the supplication of the qunut of witr, he could be lenient in this, especially if the qunut of witr is in the second half of Ramadan, because there are authentic reports from the Salaf that they used to curse the disbelievers and supplicate against them, saying: in the witr in the second half of Ramadan.
But they did not refrain from qunut in supplicating against the disbelievers in the five daily prayers. So the summary of the answer is: leaving off qunut in the five daily prayers and supplicating against the disbelievers, and transferring this supplication to the qunut of witr, is a reversal of the Sunnah. It is clear.

The questioner : Yes, it is clear.
