All Islamic doctrine is based on words of Allah and the Sunna (words and actions) of Mohammed. Allah is found in the Koran and Mohammed is found in the Sira (biography) and the Hadith (traditions). All of Islam is based on Koran, Sira, and Hadith. If it is in the Trilogy, it is Islam. If it is not in the Trilogy, then it is not Islam. To know Islam, know the Trilogy.
The problem in knowing the Trilogy is that the Koran, Sira, and Hadith were designed to be difficult to understand. There is only one way for them to be understood — they must be viewed as a systemic whole, not three separate books.
The CSPI books had to be fact-based and self-authenticating. In a sense, each book had to be a map to the original text. Nearly every paragraph in the CSPI book series has a reference number that allows the reader to go to the source text and verify what is written. If you don’t believe it or want more details, you can go the reference number and read the original.
The Sira
Here is an example from Mohammed and the Unbelievers, the Sira:
I552 The assassins’ wounded friend lagged behind, so they carried him back with them. When they got back to Mohammed, he was praying. They told him they had killed the enemy of Allah and their attack had terrorized all the Jews. There was no Jew in Medina who was not afraid.
Here is the original source text: Ishaq margin note 552:
552 Our friend al-Harith had lagged behind, weakened by loss of blood, so we waited for him for some time until he came up, following our tracks. We carried him and brought him to the apostle [Mohammed] at the end of the night. We saluted him as he stood praying, and he came out to us, and we told him that we had killed God’s enemy. He spat upon our comrade’s wounds, and both he and we returned to our families. Our attack upon God’s enemy cast terror among the Jews, and there was no Jew in Medina who did not fear for his life.
So as America is now taking in Muslims ask yourself, how is that hope and change working out for you?
