What is the Shariah ruling on an Imam who recites Qunut Al-Nazilah (calamity prayer) in every obligatory prayer for ten months, and what is the ruling on him prolonging the supplication for more than two rak'ahs? Is his supplication valid: "O Allah, liberate Al-Aqsa Mosque, and grant us prayer therein before death, and martyrdom at its thresholds"? And what is the ruling on using non-narrated supplications and persistently reciting them in Qunut Al-Nazilah?

Qunut is legislated during calamities, and it is disliked to prolong it, according to Al-Baghawi, and because lightness upon the people is required. It is not a condition for the qunut supplication to be from transmitted texts; rather, one supplicates with what is appropriate for the calamity. Sheikh al-Islam Ibn Taymiyyah stipulated the permissibility of supplicating in qunut for believers and against disbelievers, and naming those for whom or against whom the supplication is made.

As for the supplication: "O Allah, liberate Al-Aqsa Mosque, and grant us prayer therein before death, and martyrdom at its thresholds," it is not from transmitted texts. However, adding the letter 'ba' (ب) to the object in "ارزقنا فيه بصلاة" (grant us therein with prayer) is not a grammatical error. It is mentioned in "Mu'jam As-Sawāb Al-Lughawi" (Dictionary of Linguistic Correctness) that this style is acceptable, as the verb "razaqa" (to grant/provide) can be transitive by itself, or with 'min' (من), or with 'ba' (ب) in some usages.
