Daily Hadith Day 9: Fasting 9th Ramadan 1430 (30th August 2009)

Narrated Al-Bara (Radi-Allahu 'anhum):

It was the custom among the companions of Muhammad (Sallallahu 'Alaihi Wa
Sallam) that if any of them was fasting and the food was presented (for
breaking his fast), but he slept before eating, he would not eat that night
and the following day till sunset.

Qais bin Sirma-al-Ansari was fasting and came to his wife at the time of
Iftar (breaking one's fast) and asked her whether she had anything to eat.
She replied, "No, but I would go and bring some for you." He used to do
hard work during the day, so he was overwhelmed by sleep and slept. When
his wife came and saw him, she said, "Disappointment for you." When it was
midday on the following day, he fainted and the Prophet (Sallallahu 'Alaihi
Wa Sallam) was informed about the whole matter and the following verses
were revealed: "You are permitted To go to your wives (for sexual relation)
At the night of fasting." So, they were overjoyed by it. And then Allah
also revealed: "And eat and drink Until the white thread Of dawn appears to
you Distinct from the black thread (of the night)." (2.187)
