Please don't lie - you can get away with lying if people rely on you for reporting events but in a live broadcast, this is not possible.
Sarfaraz reviewed immediately after umpire raised his finger, go check the live stream; he didn't even consult with Saud.
Also, the stump cam you are talking about, at the point the bails were first dislodged (and hence the first distortion in the image from the stump cam, some part of his foot was still touching the ground). It was only the off side camera angle that showed that there perhaps was nothing grounded.
Ultimately the angle that should have decided in the favour of Sarfaraz was the leg side angle, where you could see that part of left side of his toe was grounded.
