p72.0 VIOLATING THE MECCAN SACRED PRECINCT (HARAM)
p72.1 Allah Most High says:
” … and al-Masjid al-Haram which We have appointed equally for all people, he who stays therein as well as the desert dweller. Whoever intends to violate it out of wrongdoing, We shall make him taste a painful torment” (Koran 22:25).
(n: The words out of wrongdoing in the above verse mean “by reason of doing wrong through committing an act that is forbidden therein, even if it merely consists of reviling one of the caretakers” (Tafsir al-lalalayn (y77) , 436).)
p72.2 The Prophet (Allah bless him and give him peace) said,
“Of all people, the greatest in outrage against Allah is he who kills in the Meccan Sacred Precinct, who kills someone who is not trying to kill him, or who kills because of the feuds of pre-Islamic times.”
