Asalamu Alaykum Ustadh, I was leading prayer and unintentionally missed the final ه in سمع الله لمن حمده and continued to sujood. I did not repeat it. I completed the prayer, made tasleem, then did sujood al-sahw alone so the jama‘ah wouldn’t be confused. Are my prayer and theirs valid?

Ustadh AbdulAziz al-Haqqan

Valid and u should not do sujood assahw as very obviously u have fallen into waswas.
