The legitimacy of martyrdom operations
The understanding of martyrdom operations is reserved for those to whom Allah has given understanding of religion and the genuine scale of values in the book of Allah and the Sunnah of His Messaenger ( They ask you about the sacred month - about fighting therein. Say, "Fighting therein is great [sin], but averting [people] from the way of Allah and disbelief in Him and [preventing access to] al-Masjid al-Haram and the expulsion of its people therefrom are greater [evil] in the sight of Allah. And fitnah is greater than killing." [S 2 v 217]
