Why was establishing the sunna necessary?
The Sunna, including the sayings, actions and approvals of the Prophet,
upon him be peace and blessings, which comprise one of the two main sources
of Islam, was memorized and recorded, and carefully preserved, and has been
handed down to us without any distortion or alteration. The Sunna is
included in the meaning of the verse,
Surely We have sent down the Dhikr [the collection of Divine
warnings and recitations, the Divine guidance] in parts, and surely We are
its preserver. (al-Hijr, 15.9)
The establishment of the Sunna was necessary
The Sunna is the way of life of Godís Messenger, upon him be peace and
blessings; the unique example set by him for all Muslims to follow. God sent
His Messenger to guide people to truth, to lead them in all aspects of life
and to show them how to design their life according to Godís Commandments.
The Messenger stood at the crossing-point between ignorance and knowledge,
truth and falsehood, right and wrong, and between this world and the other,
and established through all his words, his own actions and the actions he
approved, the Divine way which all Muslims must follow.
The Sunna is the window opened on the Messenger of God, the sacred way
leading to the blessings of Islam. Without the Sunna, it is impossible to
follow Islam in practical life. Only through the Sunna can a Muslim
establish a connection with Godís Messenger and receive his blessings.
Anyone who ignores the Sunna makes himself absolutely liable to deviation
and cannot remain securely within the fold of Islam. The Sunna is the most
unbreakable rope which guarantees the unity of Muslims and elevates those
who hold fast to it to Paradise.
