Permissibility of Qunut only at times of afflictions
The act done by the mentioned Imam is similar to Qunut (supplication after bowing while standing in Prayer) in the last Rak‘ah of obligatory Salah (Prayer), (Part No. 5; Page No. 398) but it is made out of place, because
Qunut should only be made in the times of affliction.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
