Dear DARahman,
Peace to you.
Are you saying that all of the People of the Scirpture during Jesus' (PBuH) time believed in Jesus (PBUH) before Jesus (PBUH) died?
No, please allow me to clarify.
I am respectfully asserting with the evidence that I have presented that all those that witnessed Prophet Jesus's ministry during their lives
would realise during or at the moment of their death the truth of Prophet Jesus's prophethood. This is irrespective of when the prophetic ministry of Jesus ended. Those that
witnessed yet
outlived the ministry of Prophet Jesus, would come to know of the truth later in their lives or certainly at the point of their death. Please also see
23:98-100 where everyone,
including disbelievers will come to recognise the truth at the point of their death.
Messengers are
always chosen from
amongst a people, who speak their language so as to make the message
clear to them (14:4) and can
only stand witness against their own people to
whom they preached. This is a concept established in the Quran (4:41; 2:143, 22:78, 40:51).
Therefore in verse 4:159, Prophet Jesus can
only stand as witness against a community he preached to. Given both the dialogue of the verses in question and the fact that Prophet Jesus can
only stand witness against his own people (5:117), the people addressed who will realise the truth of the matter are those that were present during Prophet Jesus's ministry. This is the 'against them' (alayhim) that verse 4:159 refers to.
005.117 "Never said I to them aught except what You commanded me, that 'You worship God, my Lord and your Lord'; and I was a witness over them as long as I was amongst them; then when You caused me to die, You were the Watcher over them, and You are a witness to all things" I hope that helps, God willing.
Joseph.
