"...If the party liable is mentally deficient, or weak, or unable Himself to dictate, Let his guardian dictate faithfully, and get two witnesses, out of your own men, and if there are not two men, then a man and two women, such as ye choose, for witnesses, so that if one of them errs, the other can remind her. The witnesses should not refuse when they are called on (For evidence)." - Quran 2:282 (read more)

"Abu Huraira reported Allah's Messenger (may peace be upon him) as saying: The last hour would not come unless the Muslims will fight against the Jews and the Muslims would kill them until the Jews would hide themselves behind a stone or a tree and a stone or a tree would say: Muslim, or the servant of Allah, there is a Jew behind me; come and kill him; but the tree Gharqad would not say, for it is the tree of the Jews." - Sahih Muslim 41:6985 (read more)

"Other scholars said Q. 2:256 has not been abrogated, but it had a special application. It was revealed concerning the people of the Book [the Jews and the Christians]; they can not be compelled to embrace Islam if they pay the Jizia (that is head tax on free non-Muslims under Muslim rule). It is only the idol worshippers who are compelled to embrace Islam and upon them Q. 9:73 applies ['O Prophet, struggle with the unbelievers and hypocrites, and be thou harsh with them.']. This is the opinion of Ibn 'Abbas which is the best opinion due to the authenticity of its chain of authority." - Al-Nahas
