“It is the duty of a Muslim who has anything to bequest not to let two nights pass without writing a will about it.” (Sahih al-Bukhari)
Ibn Omar (radiyAllahu anhu) then noted, “Not even one night passed me, ever since I heard this from the Prophet (sallAllahu alayhi wasallam), without having my will with me” (Bukhari, Muslim, and others).

This is a powerful Khutbah discussing the importance of securing our rights and how to write the Islamic will.
