السلام عليكم شيخ احسن الله اليكم I was late for Fajr and had to make up one rak'ah after the salam. A man crossed right in front of me twice. I didn't expect him to cross my path, so I didn't stop him with hand. Is my prayer valid, or must I repeat it? Also, does the sutrah change after the salam?

Ustadh AbdulAziz al-Haqqan

Your prayer is valid and you do not repeat it.
