Piety - Sheik Muhammed Salih Al-Munajjid - Bog

All praise is due to Allaah, the Lord of all that exists, and the
good end belongs to those who have piety. I bear witness that
there is no deity worthy of worship except Allaah the Exalted,
the Evident Truth. Allaah the Exalted is the One Who made
piety the root of the religion, as well as its clear basis. I bear
witness that Muhammad, sallallaahu 'alayhi wa sallam, is the
seal of the prophets, may Allaah the Exalted send His peace
and blessings on him until the Day of Resurrection, as well as
on all of his family and Companions
