What El Shafee Elsheikh says here is in full accord with Islamic law.
He gets justifiably irritated when the witless interviewer keeps asking him about the Beatles. She doesn’t ask him why he doesn’t listen to music. He doesn’t because Islam forbids music:
Hadith Qudsi 19:5: “The Prophet said that Allah commanded him to destroy all the musical instruments, idols, crosses and all the trappings of ignorance.” (The Hadith Qudsi, or holy Hadith, are those in which Muhammad transmits the words of Allah, although those words are not in the Qur’an.)
Muhammad also said:
(1) “Allah Mighty and Majestic sent me as a guidance and mercy to believers and commanded me to do away with musical instruments, flutes, strings, crucifixes, and the affair of the pre-Islamic period of ignorance.”
(2) “On the Day of Resurrection, Allah will pour molten lead into the ears of whoever sits listening to a songstress.”
(3) “Song makes hypocrisy grow in the heart as water does herbage.”
(4) “This community will experience the swallowing up of some people by the earth, metamorphosis of some into animals, and being rained upon with stones.” Someone asked, “When will this be, O Messenger of Allah?” and he said, “When songstresses and musical instruments appear and wine is held to be lawful.”
(5) “There will be peoples of my Community who will hold fornication, silk, wine, and musical instruments to be lawful ….” — ‘Umdat al-Salik r40.0
And regarding slavery, slavery is acceptable in Islam.
The Qur’an has Allah telling Muhammad that he has given him girls as sex slaves: “Prophet, We have made lawful to you the wives to whom you have granted dowries and the slave girls whom God has given you as booty.” (Qur’an 33:50)
Muhammad bought slaves: “Jabir (Allah be pleased with him) reported: There came a slave and pledged allegiance to Allah’s Apostle (may peace be upon him) on migration; he (the Holy Prophet) did not know that he was a slave. Then there came his master and demanded him back, whereupon Allah’s Apostle (may peace be upon him) said: Sell him to me. And he bought him for two black slaves, and he did not afterwards take allegiance from anyone until he had asked him whether he was a slave (or a free man).” (Muslim 3901)
Muhammad took female Infidel captives as slaves: “Narrated Anas: The Prophet offered the Fajr Prayer near Khaibar when it was still dark and then said, ‘Allahu-Akbar! Khaibar is destroyed, for whenever we approach a (hostile) nation (to fight), then evil will be the morning for those who have been warned.’ Then the inhabitants of Khaibar came out running on the roads. The Prophet had their warriors killed, their offspring and woman taken as captives. Safiya was amongst the captives. She first came in the share of Dahya Alkali but later on she belonged to the Prophet. The Prophet made her manumission as her ‘Mahr.’” (Bukhari 5.59.512) Mahr is bride price: Muhammad freed her and married her. But he didn’t do this to all his slaves:
Muhammad owned slaves: “Narrated Anas bin Malik: Allah’s Apostle was on a journey and he had a black slave called Anjasha, and he was driving the camels (very fast, and there were women riding on those camels). Allah’s Apostle said, ‘Waihaka (May Allah be merciful to you), O Anjasha! Drive slowly (the camels) with the glass vessels (women)!’” (Bukhari 8.73.182) There is no mention of Muhammad’s freeing Anjasha.
“British ISIS ‘Beatle’ El Shafee Elsheikh in Interview from Captivity: I Don’t Denounce Slavery, Nothing Beats the West for Corruption,” MEMRI, April 8, 2018:
El Shafee Elsheikh, a member of the British ISIS cell known as the “Beatles,” which became notorious for its beheading videos of foreign hostages, gave an interview to journalist Jenan Moussa of Alaan TV from his cell. Elsheikh, who refused to answer questions regarding the charges against him, citing the “ongoing legal process,” said that he did not agree with everything ISIS did. When pressed by Moussa as to what things he opposed, he responded: “Traffic tickets… such things that have no basis in the law of Allah. ” With regard to the enslavement of Yazidi women, Elsheikh said: “I don’t denounce slavery. … Just because America decided to abolish something… It does not mean that every person has to run behind America and say: This is now an abominable act.” He further said that he decided to travel to Syria because of the oppression of Muslims worldwide. “Every environment has corruption, but nothing beats the West,” he said. The Sudanese-born Elsheikh, who was raised in London, is being held by the Kurdish-led Syrian Democratic Forces since his capture in January in eastern Syria, along with another member of the ISIS cell.
