What did Prophet Muhammad (peace be upon him) say regarding protection of Mecca on the day of the Conquest?
 Narrated Sa`id bin Abu Sa`id Al-Maqburi:                     Abu Shuraih, Al-`Adawi said that he had said to `Amr bin Sa`id when he was sending the troops to Mecca (to fight `Abdullah bin Az-Zubair), "O Chief! Allow me to tell you what Allah's Apostle said on the day following the Conquest of Mecca. My ears heard that and my heart understood it thoroughly and I saw with my own eyes the Prophet when he, after Glorifying and Praising Allah, started saying, 'Allah, not the people, made Mecca a sanctuary, so anybody who has belief in Allah and the Last Day should neither shed blood in it, nor should he cut down its trees. If anybody tells (argues) that fighting in it is permissible on the basis that Allah's Apostle did fight in Mecca, say to him, 'Allah allowed His Apostle and did not allow you.' "Allah allowed me only for a few hours on that day (of the conquest) and today its sanctity is valid as it was before. So, those who are present should inform those who are absent (concerning this fact." Abu Shuraih was asked, "What did `Amr reply?" He said, (`Amr said) 'O Abu Shuraih! I know better than you in this respect Mecca does not give protection to a sinner, a murderer or a thief."
