Abu Dawud
Prayer
Book Number: 002 / Hadith Number: 444
Narated By Amr ibn Umayyah ad-Damri : We were in the company of the Apostle of Allah (pbuh) during one of his journeys. He overslept abandoning the morning prayer until the sun had arisen. The Apostle of Allah (pbuh) awoke and said: Go away from this place.
He then commanded Bilal to call for prayer. He called for prayer. They (the people) performed ablution and offered two rak'ahs of the morning prayer (sunnah prayer). He then commanded Bilal (to utter the iqamah, i.e. to summon the people to attend the prayer). He announced the prayer (i.e. uttered the iqamah) and he led them in the morning prayer.
