Repeating the sunnahs if fardh needs to be repeated

After offering the fardh and sunnah rak’ahs for dhuhr salah, if a person realizes that the salah was invalid due to some reason (for example, he or the imam did not have wudu when offering the fardh salah) must he repeat just the fardh salah, or the sunnah salah along with it?

 بسم الله الرحمن الرحيم

الجواب حامدا ومصليا ومسلما

In the aforementioned scenario, if one receives the news within the time of Dhuhr, they must repeat the fardh salah and the two rak’ahs of sunnah after the fardh; they would not have to repeat the four rak’ahs of sunnah before the fardh. However, if one found out after the salah time was over, they will only have to repeat the fardh salah. 

والله اعلم

Allah Knows best.
