A man joined the salah late, and the Imam prayed 5 rakaat instead of 4, but did not perform sujud-as-sahw. The imam and congregation repeated the salah, but the man who joined late did not as he had prayed 4 rakaat, not 5. Is the salah of the late man valid?

Ustadh AbdulAziz al-Haqqan
2 sayings for the people of ilm and Imam Ibn Uthaymeen mentioned that it is valid and Allah know best.
