Assalaamu Alaikum wa rahmathullahi wa barakaathuhu. Sheikh if I missed the first two rakats of duhr prayer with imam, and I make a mistake in my prayer after the imam completes the prayer, should I do sajda suhw? Kindly explain in the case where my mistake was made before the imam's salam as well.

Ustadh AbdulAziz al-Haqqan

Yes you do sujud assahw
