(O ye who believe! Ye have charge of your own souls. He who erreth cannot injure you if ye are rightly guided) [5:105].
Al-Kalbi reported from Abu Salih who related that Ibn 'Abbas said: “The Messenger of Allah sent a letter to the people of Hajar, whose chief was Mundhir ibn Sawa, inviting them to Islam, or to pay the Jizyah if they chose not to embrace Islam. When Mundhir ibn Sawa received the letter, he showed it to the Arabs, Jews, Christians, Sabeans and Magians who were around him. They all agreed to pay the Jizyah and disliked embracing Islam. The Messenger of Allah, Allah bless him and give him peace, wrote back to him, saying: 'As for the Arabs, do not accept from them except Islam otherwise they will have nothing but the sword. As for the people of the Book and the Magians, accept the Jizyah from them. When this letter was read to them, the Arabs embraced Islam while the people of the Book and the Magians agreed to pay the Jizyah. The hypocrites among the Arabs said: 'How strange from Muhammad! He claims that Allah has sent him to fight all people until they surrender to Allah and does not accept the Jizyah except from the people of the Book. But we only see that he has accepted from the idolaters of the people of Hajar that which he had rejected from the Arab idolaters'. Allah, exalted is He, then revealed (O ye who believe! Ye have charge of your own souls. He who erreth cannot injure you if ye are rightly guided), i.e. who errs from amongst the people of the Book”.
