Khalid b. Sumair said:
'Abd Allah b. Rabah al-Ansari, whom the Ansar called faqih (juries), came to us from Medina, and reported us on the authority of Abu Qatadah al-Ansari, the horseman of the Messenger of Allah ﷺ saying: The Messenger of Allah ﷺ sent a military expedition consisting of the chief Companions. He then narrated the same story, saying Nothing awakened us except the rising sun. We stoop up in bewilderment, for our prayer. The Prophet ﷺ said: Wait a little, wait a little. When the sun rose high, the Messenger of Allah ﷺ said: Those who sued to observer the two rak'ahs of Fajr prayer (sunnah prayer before obligatory prayer) should observe them. Then those who used to observe and those who would not observe stood up and said prayer. Then the Messenger of Allah ﷺ commanded to call for prayer; the call for prayer was made accordingly. The Messenger of Allah ﷺ stood and led us in prayer. When he turned away (from the prayer) he said: We thank Allah for the fact that we were not engaged in any wordily affairs which detained us from our prayer. Instead our souls were in the hands of Allah. He released them whenever He wished. If any one of you gets morning prayer tomorrow at its proper time, he should offer a similar prayer as an atonement.
