Two British terrorists who fled the United Kingdom to fight in Syria ordered the books Islam For Dummies, The Koran For Dummies and Arabic For Dummies from Amazon ahead of their trip.
Mohammed Nahin Ahmed also told his childhood friend Yusuf Zubair Sarwar, both 22, 'I cannot tell anyone I'm going to jihad. Lol. I'll get arrested' before they left Birmingham and joined rebels in Aleppo, a court heard today.
After eight months fighting in Syria they were arrested on their return to Heathrow Airport in January after their relatives tipped off counter-terrorism detectives.
Sarwar had left a note for his mother that he was going 'to do jihad' in Syria was 'doing the best deed in Allah's eyes'. He said the Taliban and Al Qaeda 'are not bad', so she went to the police.
After returning to Britain they told officers they had been doing humanitarian work but a camera containing 'thousands' of images, including some of them posing with guns on the front line, was found in their luggage.
