Adding to the Qunoote Naazilah

Q: Salaah-622: When our Imaam recites the Qunoote Naazilah, he adds some words to it. The Qunoote Naazilah he recites is:
Fatawa Rahimiyyah Du?aa (vol.2 pg. 480)

Since this du'aa has several additions, if is correct to recite it?

Answer: In a narration from Hadhrat Abu Hurayrah RADI., Rasulullaah SAW.. stated that the Imaam should make the salaah brief because there are weak and old people following him. When performing salaah by himself, he may then perform the salaah as long as he pleases. Since the addition to the du'aa extends the salaah, it should not be made a habit even though there is no harm in reciting it when the occasion permits And Allaah knows best what is most correct.
