Morality in Islam to every muslim is based on the Koran. I am a Christian,and my morality is based on the Bible.
In the world today,we see terrorism common in almost all Islamic nations including Nigeria (Many will not agree with me on this,how many words relate to Christianity in the Nigerian constitution? How many relates to Islam?).
.
Now,to basics. The person who laid the foundation to terrorism was Mohammed the prophet of Islam. Following are allah's command to him,and the message of Islam:
Quran2vs191-193,244,216; 3vs56,151; 4vs76,89,95,104; 5vs33; 8vs12,15,39,57,67,59-60,65; 9vs5,14,20,29,33,30,38-39,41,42,73,88,111,123; 17vs16 Etc.

Remember the words of Jesus,
"Blessed are the peacemakers:for they shall be called the children of God.
Blessed are they which are persecuted for righteousness' sake:for theirs is the kingdom of heaven.
Blessed are ye,when men shall revile you,and persecute you...
Rejoice,and be exceeding glad:for great is your reward in heaven.." Matthew5:9-12
.

Jesus said ".. Love your enemies,bless them that curse you,do good to them that hate you, and pray for them which despitefully use you." Matthew5:44
But Mohammed preached hatred.
Morally, who is more upright, Mohammed or Jesus? Who should be followed?
