Imran bin Husain said: The Messenger of Allah ﷺ was on his journey. They (the people) slept abandoning the Fajr prayer. They awoke by the heat of the sun. Then they travelled a little until the sun rose high. He (the Prophet) commanded the muadhdhin (one who called for prayer) to call for prayer. He then offered two rak'ahs of prayer (sunnah prayer) before the (obligatory) fajr prayer. Then he (the muadhdhin) announced for saying the prayer in congregation (i. e. he uttered iqamah). Then he led them in the morning prayer.

Narrated Amr ibn Umayyah ad-Damri: We were in the company of the Messenger of Allah ﷺ during one of his journeys. He overslept abandoning the morning prayer until the sun had arisen. The Messenger of Allah ﷺ 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.

Dhu Mikhbar al-Habashi, who used to serve the Prophet ﷺ, reported a version of the previous tradition. The Prophet ﷺ performed ablution in such a way that there is no mud on the earth.

This is narrated by Hajjaj on the authority of Yazid bin Sulaih from Dhu Mikhbar from a person of al-Habashah (Ethiopia). Ubaid (a narrator) said: Yazid bin Salih (instead of Yazid bin Sulaih).

This tradition has also been transmitted through another chain of narrators by Dhu Mikhbar, the nephew of the Negus. This version adds: "He (Bilal) called for prayer unhurriedly. "

He said: Anyone who oversleeps or forgets (prayer) should do similarly.
