Non-Muslims paying for the upkeep of Muslims, willingly or unwillingly, is a Qur’anic dictate:
“Fight those who believe not in Allah nor the Last Day, nor hold that forbidden which hath been forbidden by Allah and His Messenger, nor acknowledge the religion of Truth, (even if they are) of the People of the Book, until they pay the Jizya with willing submission, and feel themselves subdued” (Qur’an 9:29).
The caliph Umar said the jizya payments from the dhimmis were the source of the Muslims’ livelihood:
“Narrated Juwairiya bin Qudama at-Tamimi: We said to `Umar bin Al-Khattab, ‘O Chief of the believers! Advise us.’ He said, ‘I advise you to fulfill Allah’s Convention (made with the Dhimmis) as it is the convention of your Prophet and the source of the livelihood of your dependents (i.e. the taxes from the Dhimmis.)’” (Bukhari 4.53.388)
Jihad preacher Anjem Choudary said in February 2013:
“We are on Jihad Seekers Allowance, We take the Jizya (protection money paid to Muslims by non-Muslims) which is ours anyway. The normal situation is to take money from the Kafir (non-Muslim), isn’t it? So this is normal situation. They give us the money. You work, give us the money. Allah Akbar, we take the money. Hopefully there is no one from the DSS (Department of Social Security) listening. Ah, but you see people will say you are not working. But the normal situation is for you to take money from the Kuffar (non-Muslim) So we take Jihad Seeker’s Allowance.”
“How I was indoctrinated to wage war against Nigeria — Boko Haram Commander,” by Ifeanyi Okolie, Vanguard, January 5, 2019 (thanks to The Religion of Peace):
A top commander of the Boko Haram Sect, Umar Abdulmalik, who was arrested penultimate Thursday by operatives of the Inspector General of Police Special Intelligence Response Team, IRT, in Lagos State, for carrying out several bombings, bank robberies and killings within the Federal Capital Territory, FCT, Abuja, Owo, Ondo State and Lokoja Kogi State, has revealed how he joined the sect and led members to carry out these attacks….
“I joined one of the Boko Haram cells in Okene headed by one Zeeidi and we carried out several bombings within Kaduna, Kano and Abuja. Zeeidi was the person providing the bombs and my job then was to take them to our target locations. After a while, the Department of State Security infiltrated our cell and they started arresting members of our group. Mallam Mustapha was arrested and his mosque was demolished. Zeedi brought the idea of bank robbery so that those of us who have not been arrested could have resources to continue with the jihad. He brought some guns and he suggested we should attack the Kotonkarfe Prison in Kogi State, so we could free our members who were detained there. The attack on the prison was successful and we freed a lot of our members, after which we attacked some banks in Okene and took all the money we could find there.
“We then moved to Owo where we robbed some of the banks with dynamites and carted away large sums of money. We used some of the money we made from those robberies to buy high explosives including materials we could use in producing non-metallic bombs that could beat metal detectors. A lot of our members including Zeedi were arrested after those bank robberies and the attack on prison. We’re open for business, says U.S. Embassy in Nigeria Then, I moved to Abuja with the bombs we produced and I formed a new cell in 2014. We carried out several bombings in the Fedeal [sic] Capital territory including those at Banex Plaza, Nyanya and Kuje areas of Abuja. Unfortunately our gang was busted and five of our gang members were arrested while our bombs, including the non-metallic and the materials we were using in making them were recovered. I escaped, fled to Kano and I went underground for two years before I returned to Abuja and formed a new gang and we went into full blown armed robbery.”…
