Asalam alikm wa rahmatullah wa barakhtu' the question is I prayed fajir in masjid jama'a the imam mistaked the ayah rather than saying و قد احاطه به كل شي علما he said the last part قدرا then he went to ruku and finished the salah without sajda sahu is the prayer valid? May allah bless you

Ustadh AbdulAziz al-Haqqan

Yes, the Salah is valid.
