"Also (forbidden are) women already married, except those whom your right hands possess. Thus has Allah ordained for you. All others are lawful, provided you seek them from your property, desiring chastity, not fornication. So with those among them whom you have enjoyed, give them their required due, but if you agree mutually after the requirement (has been determined), there is no sin on you. Surely, Allah is Ever All-Knowing, All-Wise." - Quran 4:24 (read more)

"If war is waged anywhere to achieve this goal, namely to free the occupied lands of the laws and the tyranny of disbelievers, it is undoubtedly a case of Jihad for the sake of Allah. It thus needs to be financed from the money of Zakah, the amount of which is to be decided based on the total sum of the charity, the requirements of Jihad as well as the degree of the need of other potential recipients of charity." - Yusuf al-Qaradawi
