one goes to jannah isA when praying 4 rakats sunnah before and after dhur. Does this count also when praying instead of sunnah 4 rakats qada before and after dhur? As for shafii school sunnah should not be prayed while having qada.
By praying at those times one is still meeting the wording of the hadith; so just do and leave questioning.
