ٱلسَّلَامُ عَلَيْكُمْ وَرَحْمَةُ ٱللَّٰهِ وَبَرَكَاتُهُ أحسن الله إليكم A brother asks: "I am in a Muslim school. When we pray together, sometimes my wudoo breaks or I miss a rukn. But I don't want to cause issues, so I pretend to pray. I make it up later. What is the ruling on this?"

Ustadh AbdulAziz al-Haqqan
No, this is not allowed. Get out of the Salah, go make wudu, and come back and pray.
