Trinitarians "know" that Jesus is God, however that does not make what they "know" any more true than you "know" that Muhammad attacked innocent Jews because they broke a treaty. Also since this thread concerns Muhammad not Moses your attempt to attack a straw man only demonstrates you cannot establish the truth of your traditions.
Muslims consistently accuse Christians of taking parts of the Qur'an out of context while consistently taking verses of the Bible out of context. There is not a single NT Scripture that tells Christians to take their own revenge over broken treaties or to wage war with those who reject the Gospel of the Kingdom of God. In fact Jesus told the 70 he sent to proclaim the Gospel:
Matthew 10:12-15
12 "And as you enter the house, give it your greeting. 13 "And if the house is worthy, let your greeting of peace come upon it; but if it is not worthy, let your greeting of peace return to you. 14 "And whoever does not receive you, nor heed your words, as you go out of that house or that city, shake off the dust of your feet. 15 "Truly I say to you, it will be more tolerable for the land of Sodom and Gomorrah in the day of judgment, than for that city. NAS
Mark 6:10-11
10 And He said to them, "Wherever you enter a house, stay there until you leave town. 11 "And any place that does not receive you or listen to you, as you go out from there, shake off the dust from the soles of your feet for a testimony against them." NAS
Urban II took a leaf from Muhammad's play book in 1095 when he instigated the Crusades.
The Trinity is a myth so why discuss a myth?
