Asalaamu alaykum brother,
A couple of thoughts:
1.) With regards to Allah (swt) having body parts, there are not any Sunnis that believe Allah (swt) has body parts in the way that humans do. When I was a Shia, I read a (Sunni) narration about how Allah (swt) has a right hand and two left feet, or something absurd like that. This type of thought is simply not found in the Sunni school. Even those Sunnis that "anthropomorphise" (i.e. affirm Allah's attributes in their literal meaning) do not believe that Allah (swt) has parts like we humans do, they believe that he has parts that are befitting of his majesty. And, I would guess that even this is a minority opinion, in that I have yet to meet somebody that I know openly professes this view. Most Sunnis either interpret the physical attributes of Allah (swt) in non-physical ways, or refuse to do taweel at all, and profess that only Allah (swt) knows the meaning of these verses. This is my position. To give an example, we have explicit ahadeeth from the Prophet (saws) in regards to the Angel Gabriel (as). He (as) has 600 wings and when the Prophet (saws) looked around, no matter what direction he looked, Gabriel (as) was filling the horizon with his "body". Now, to any rational person, this does not make sense. An angel with 600 wings, okay, no problem. But his presence is always filling the horizon in all directions? That would mean that Gabriel (as) is in the shape of a circle, with his body cut out in the middle. Despite this being the only logical physical explanation, do you see anybody that professes this view? I don't. Rather, people affirm what has been said about Angel Gabriel (as) and leave the details up to Allah (swt) because our tiny brains can't comprehend the true nature of these other beings, let alone the true nature of Allah (swt) who created Gabriel (as).
2.) Killing of any innocent person is absolutely forbidden and a major sin. The Qur'an references the law of Musa (as) and says that taking one innocent life is equal to destroying all of humanity. The killing of a Muslim is even worse.
3.) Avoid Dr Zakir Naik. I am sure he is an excellent physician and a sincere Muslim, but at the end of the day, he is only a lecturer, and (in my humble opinion), not the best one to be listening too. There are real scholars that have lectures on YouTube, if that is your preferred method of learning. A better way is to read the words of the scholars, for which there are many websites.
