Avoid Wajdi al-Akkari as he is extremely divisive and has a confrontational attitude. Brother Nouman Ali Khan doesn't talk about issues of fiqh, last I checked, so he will be of benefit. As for raising hands, it is not an essential aspect of salah. Since you're a Hanafi, it is best that you do NOT do rafa' yadain. If you were a Shafi'i or a Hanbali, then it would be better for you to do rafa' yadain. Even the Malikis do not do rafa' yadain. Proof from sunnah exist for both opinions.
