A man who prays Fajr and then finds that he prayed it while it was still night

Ibn Sirin said: I have been told that Sayyiduna Abu Musa al-Ash'ari (may Allah be pleased with him) repeated the Fajr prayer three times in one day. He prayed and sat down, and it became clear that he had prayed before dawn, so he repeated the prayer. Then he prayed and sat down, and it became clear that dawn had still not broken, so he prayed it a third time.

Nafi' said: Sayyiduna Ibn Umar (may Allah be pleased with them both) repeated the Fajr prayer three times in one day at Jam' (Muzdalifah). He finished the prayer and it became clear that he had prayed before dawn, so he repeated the prayer. Then he prayed and finished, and it became clear that dawn had still not broken, so he prayed it a third time.

Al-Hasan said: In the time of Sayyiduna Abdullah bin Abbas, the people were in doubt about whether dawn had broken. He ordered his muezzin, who called the iqamah, and Sayyiduna Ibn Abbas (may Allah be pleased with them both) stepped forward and led the prayer. He recited the whole of Surah al-Baqarah, then bowed, then prostrated, then stood for the second rak'ah and recited the whole of Surah Al Imran. Then he bowed and then prostrated. When they finished the prayer, it had become light.

Ibrahim said: Once I had a cough when I went out for the Fajr prayer. The muezzin heard the sound of my cough and thought that morning had come. He called the iqamah and we prayed the Fajr prayer. Then we saw that dawn had not yet broken, so we prayed again after dawn had broken.
