Praise be to Allah, the Lord of the World; and blessings and peace be upon our Prophet Muhammad and upon all his Family and Companions. The Witr prayer is Sunnah Mukkadah (confirmed Sunnah). This is the preponderant opinion of the Muslim scholars. It is not an obligatory prayer like the other five obligatory prayers.
Muadh ibn Jabal was a young man growing up in Yathrib as the light of guidance and truth began to spread over the Arabian Peninsula. He was a handsome and imposing character with black eyes and curly hair and immediately impressed whoever he met.
He was already distinguished for the sharpness of his intelligence among young men of his own age. The young Muadh became a Muslim at the hands of Musiab ibn Umayr, the da'iy (missionary) whom the Prophet had sent to Yathrib before the hijrah.
