Hazrat Qatan narrates that during the time of Hazrat Muawiyah, people broke their Ramadan fast before sunset, so Hazrat Muawiyah ordered them to make up (qada) the fast.

Hazrat Ibn Jurayj says that I asked Hazrat Ata: I broke my fast in Ramadan on a cloudy day thinking that the sun had set, but then the sun appeared. Should I make up this fast and not give expiation? He replied: Do just that.

Hazrat Abu Ishaq says that I was in the land of Rome with Hazrat Ziyad bin Nadr. We saw the crescent of Ramadan, so the people fasted, among whom were Hazrat Abdullah, Amir bin Sa’d, Sami’, Abu Abdullah, Abu Ma’mar, and Abu Masaafi’. The people fasted for one day; on that day there were clouds in the sky. We were between two mountains named Harith and Huwairith. I did not break my fast until the night became apparent. Then the sun rose and we saw it on the mountains. So Ziyad said that we will make up this day and we did not count this fast.

Hazrat Aslam narrates that Hazrat Umar broke his fast in the month of Ramadan, and it was said to him that the sun has risen! Hazrat Umar replied that this is a minor mistake, we made every effort, therefore there is no sin upon us.

Hazrat Muslim narrates that a man came to Hazrat Ibn Abbas (may Allah be pleased with them) to ask about suhoor. One of Hazrat Ibn Abbas’s companions said to him,“Do not eat at the time when you are in doubt.”Hazrat Ibn Abbas (may Allah be pleased with them) said,“He has said nothing; eat as long as you are in doubt, until there is no doubt left.”

Hazrat Awn bin Abdullah narrates that two men came to Hazrat Abu Bakr while he was eating suhoor. One of them said that Fajr has begun. The other said that Fajr has not yet begun. Hazrat Abu Bakr said: Eat, there is a difference of opinion between the two.

It is narrated in the same way from Hazrat Abu Bakr through another chain of transmission.

Hazrat Mak'hool narrates that I saw Hazrat Ibn Umar (may Allah be pleased with them both) draw a bucket of water from the well of Zamzam. He asked two men, "Has Fajr dawned?" One of them said, "No," and the other said, "Yes." Upon this, Hazrat Ibn Umar (may Allah be pleased with them both) drank the water.

Ibrahim says: Eat until the light is in the form of width.

Hazrat Ikrimah says: Eat until there appears on the horizon a form like the tearing of a sheet.
