Fatawa of Ayatullah al Uzama Syed Ali al-Husaini Seestani
1127. It is also Mustahab that while reciting qunut, a person keeps his hands in front of his face, turning the palms facing the sky, and keeping both, the hands and the fingers, close together. It is Mustahab to look at the palms in qunut.
1129. It is Mustahab that qunut is recited loudly. However, if a person is offering prayers in congregation, and if the Imam can hear his voice, it will not be Mustahab for him to recite qunut loudly.
1130. If a person does not recite qunut intentionally, there is no qadha for it. And if he forgets it, and remembers before reaching Ruku, it is Mustahab that he should stand up and recite it. And if he remembers while performing Ruku, it is Mustahab that he should perform its qadha after Ruku. And if he remembers it while performing Sajdah, it is Mustahab that he should perform its qadha after Salam.
