Narrated `Aisha: (At times) in Ramadan the Prophet used to take a bath in the morning not because of a wet dream and would continue his fast.

Narrated Abu Bakr bin `Abdur-Rahman: My father and I went to `Aisha and she said, "I testify that Allah's Apostle at times used to get up in the morning in a state of Janaba from sexual intercourse, not from a wet dream and then he would fast that day."

Then he went to Um Salama and she also narrated a similar thing.

Narrated Abu Huraira: The Prophet said, "If somebody eats or drinks forgetfully then he should complete his fast, for what he has eaten or drunk, has been given to him by Allah."

Narrated Humran: I saw `Uthman performing ablution; he washed his hands thrice, rinsed his mouth and then washed his nose, by putting water in it and then blowing it out, and washed his face thrice, and then washed his right forearm up to the elbow thrice, and then the left-forearm up to the elbow thrice, then smeared his head with water, washed his right foot thrice, and then his left foot thrice and said, "I saw Allah's Apostle performing ablution similar to my present ablution, and then he said, 'Whoever performs ablution like my present ablution and then offers two rak`at in which he does not think of worldly things, all his previous sins will be forgiven."

Narrated `Aisha: A man came to the Prophet and said that he had been burnt (ruined). The Prophet asked him what was the matter. He replied, "I had sexual intercourse with my wife in Ramadan (while I was fasting)." Then a basket full of dates was brought to the Prophet and he asked, "Where is the burnt (ruined) man?" He replied, "I am present." The Prophet told him to give that basket in charity (as expiation).
