when it is said to them believe in what allah has sent down they reply we believe in what was sent down to us but they disbelieve in what is sent after it although it is the truth confirming their own book. say why before did you kill the prophets of allah if you are believers
وإذا قيل لهم آمنوا بما أنزل الله قالوا نؤمن بما أنزل علينا ويكفرون بما وراءه وهو الحق مصدقا لما معهم قل فلم تقتلون أنبياء الله من قبل إن كنتم مؤمنين
