"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)

"Offering condolences to a kaafir if one of his loved ones – a friend or relative – dies... Some of the scholars say that it is haraam to offer condolences to them, and some say that it is permissible. Some of them added further details and said that if that serves an interest, such as the hope that they may become Muslim and it may ward off their evil which could not be done except by offering condolences, then it is permissible, otherwise it is haraam." - Muhammad Saed Abdul-Rahman
