Killing Messengers
The Children of Israel were repeatedly warned, yet whenever messengers came with truths they disliked, they rejected some and killed others.
2:87And verily We gave unto Moses the Scripture and We caused a train of messengers to follow after him, and We gave unto Jesus, son of Mary, clear proofs (of Allah's sovereignty), and We supported him with the Holy spirit. Is it ever so, that, when there cometh unto you a messenger (from Allah) with that which ye yourselves desire not, ye grow arrogant, and some ye disbelieve and some ye slay?
5:70We made a covenant of old with the Children of Israel and We sent unto them messengers. As often as a messenger came unto them with that which their souls desired not (they became rebellious). Some (of them) they denied and some they slew.
Say, 'If you truly believed in your scripture, why did you kill the prophets unjustly?'
2:91And when it is said unto them: Believe in that which Allah hath revealed, they say: We believe in that which was revealed unto us. And they disbelieve in that which cometh after it, though it is the truth confirming that which they possess. Say (unto them, O Muhammad): Why then slew ye the prophets of Allah aforetime, if ye are (indeed) believers?
3:183(The same are) those who say: Lo! Allah hath charged us that we believe not in any messenger until he bring us an offering which fire (from heaven) shall devour. Say (unto them, O Muhammad): Messengers came unto you before me with miracles, and with that (very miracle) which ye describe. Why then did ye slay them? (Answer that) if ye are truthful!
