Ma'tmar bin Sulaiman-al-Taufayl معتمر بن سليمان - الطفيل · The Book of Jihad

"I have been commanded to fight the people until they say La ilaha illallah (there is non worthy or worship except Allah). Whoever says it, his life and his property are safe from me, except for its right, and his reckoning will be with Allah."

"Whoever fights seeking only an 'Iqbal, then he will have what he intended."
