Prophets Killed

In this post I list verses that speak of the killing of prophets specifically.

S 2:61 And when you said: Musa, we shall not be patient with one food so invoke your lord for us to bring out for us of what the Earth grows, of its green plants and its cucumbers and its fum and its lentils and its onions. He said: Would you replace that which is lower with that which is better? Go down to Egypt. Then you will have what you have asked for. And humiliation and destitution were struck upon them and they returned with anger from Allah. That is because they used to disbelieve in the signs of Allah and kill the prophets without right. That is because they disobeyed and were transgressing.

Go down to Egypt? But hadn't they just left Egypt?

S 2:91 And when it was said to them: Believe in what Allah has sent down, they said: We believe in what was sent down upon us. And they disbelieve in what is behind it, when it is the truth confirming what they have. Say: So why do you kill Allah’s prophets before, if you are believers?

The author uses the imperfect (non-past) tense. If this is in the past, then he should have said 'why did you kill...?'

S 3:21 Those who disbelieve in Allah’s verses and kill the prophets without right and kill those who command equity among people--give them good news of painful torture.

S 3:112 Humiliation has been struck upon them wherever they have been met with except with a rope from Allah and a rope from people. And they came back with anger from Allah and poverty was struck upon them. That is because they used to disbelieve in Allah’s verses and they kill the prophets without right. That is because they have disbelieved and used to transgress.

But wasn't the founder of Islam the last prophet?

S 3:181 Allah has heard the speech of those who have said: Allah is poor and we are rich. We shall write what they have said and their killing the prophets without right and say: Taste the torture of the fire.

S 4:155 So because of their breaking their covenant and their kufr in Allah’s verses and their killing the prophets without right and their saying: Our hearts are uncircumcised. Rather, Allah has stamped them for their kufr so they do not believe except a few.
