Hadith.935 - Zurarah narrated that Imam عليه السلام said:
"Qunoot (supplication) is in all prayers."
Shaykh Muhammad ibn al-Hasan ibn Ahmad ibn al-Walid narrated from Sa'd ibn Abdullah that he would say it is not permissible to make du'a (supplication) in Qunoot in Persian, whereas Muhammad ibn al-Hasan al-Saffar would say it is permissible. I [the author] say it is permissible.
