First thing firsts

There is a tartib to be followed - first things first.

Prayer is incomplete without wudhu' (ablution) and ablution starts with niyyah (intention).

Every act to be undertaken by a Muslim should commence with the basmalah. A new Muslim starts with shahadah. A new born baby should hear the adhan.

So is the Islamic Law. No one can just pronounce anyone guilty without due process. And the pronouncement of a mob is not part of due process.

No one can just issue a fatwa (ruling) except one qualified to do so. Qualification to issue fatwa is not self-ascribed, it is based on institutional arrangement, i.e. the Office of Mufti or the Darul-Iftah.

No one can just proclaim jihad ashgar. This is a communal responsibility, not an selective individual option. The declaration is incumbent on the community Imam (Leader), not just on anyone who have studied the law.

This is the beauty of the concept of tartib, there is order to every undertaking, there is progression. Islam is a religion of order and serenity; not a religion of chaos and mob.
