John Stott has written about the Muslim attitude towards the cross of Christ:-
One of the saddest features of Islam is that it rejects the cross, declaring it inappropriate that a major prophet of God should come to such an ignominious end. The Koran sees no need for the sin-bearing of a Saviour. At least five times it declares categorically that “no soul shall bear another’s burden’. Indeed, “if a laden soul cries out for help, not even a near relation shall share its burden”. Why is this? It is because “each man shall reap the fruits of his own deeds”, even though Allah is merciful and forgives those who repent and do good. Denying the need for the cross, the Koran goes on to deny the fact. The Jews “uttered a monstrous falsehood” when they declared “we have put to death the Messiah Jesus the son of Mary, the apostle of Allah”, for “they did not kill him, nor did they crucify him, but they thought they did”.
