One may begin to fast even after having intimacy

I heard Abu Huraira (Allah be pleased with him) narrating that he who is overtaken by dawn in a state of seminal emission should not observe fast. I made a mention of it to 'Abd al-Rahman b. Harith (i. e. to his father) but he denied it. 'Abd al-Rahman went and I also went along with him till we came to'A'isha and Umm Salama (Allah be pleased with both of them) and Abd al-Rahman asked them about it.

Both of them said: (At times it so happened) that the Messenger of Allah ﷺ woke up in the morning in a state of junub (but without seminal emission in a dream) and observed fast.

He (the narrator) said: We then proceeded till we went to Marwan and Abd al-Rahman made a mention of it to him. Upon this Marwan said: I stress upon you (with an oath) that you better go to Abu Huraira and refer to him what is said about it. So we came to Abu Huraira and Abu Bakr had been with us throughout and 'Abd al-Rahman made a mention of it to him, whereupon Abu Huraira said: Did they (the two wives of the Holy Prophet) tell you this? He replied: Yes Upon this (Abu Huraira) said: They have better knowledge. Abu Huraira then attributed that what was said about it to Fadl b. 'Abbas and said: I heard it from Fadl and not from the Messenger of Allah ﷺ. Abu Huraira then retracted from what he used to say about it. Ibn Juraij (one of the narrators) reported: I asked 'Abd al-Malik, if they (the two wives) said (made the statement) in regard to Ramadan, whereupon he said: It was so, and he (the Holy Prophet) (woke up in the) morning in a state of junub which was not due to the wet dream and then observed fast.  

كَانَ النَّبِيُّ ﷺ يُصْبِحُ جُنُبًا مِنْ غَيْرِ حُلُمٍ ثُمَّ يَصُومُ  

Yahya related to me from Malik from Sumayy, the mawla of Abu Bakr ibn Abd ar-Rahman ibn al-Harith ibn Hisham that he heard Abu Bakr ibn Abd ar-Rahman ibn al-Harith ibn Hisham say, "My father and I were with Marwan ibn al Hakam at the time when he was amir of Madina, and someone mentioned to him that Abu Hurayra used to say, 'If someone begins the morning junub, he has broken the fast for that day.' Marwan said, 'I swear to you, Abdar-Rahman, you must go to the two umm al muminin, A'isha and Umm Salama, and ask them about it.' ''Abd ar-Rahman went to visit A'isha and I accompanied him. He greeted her and then said, 'Umm al-muminin, we were with Marwan ibn al Hakam and someone mentioned to him that Abu Hurayra used to say that if some one had begun the morning junub, he had broken the fast for that day.' A'isha said, 'It is not as Abu Hurayra says Abd ar-Rahman. Do you dislike what the Messenger of Allah ﷺ used to do?', and Abd ar-Rahman said, 'No, by Allah.' A'isha said, 'I bear witness that the Messenger of Allah ﷺ used to get up in the morning junub from intercourse, not a dream, and would then fast for that day.' " He continued, "Then we went and visited Umm Salama, and Abd ar- Rahman asked her about the same matter and she said the same as A'isha had said. Then we went off until we came to Marwan ibn al-Hakam Abd ar-Rahman told him what they had both said and Marwan said, 'I swear to you, Abu Muhammad, you must use the mount which is at the door, and go to Abu Hurayra, who is on his land at al Aqiq, and tell him this.' So Abd ar-Rahman rode off, and I went with him, until we came to Abu Hurayra. Abd ar-Rahman talked with him for a while, and then mentioned the matter to him, and Abu Hurayra said, 'I don't know anything about it. I was just told that by someone.'"

[Machine] Abu Hurairah said: "Whoever wakes up in a state of janabah (ritual impurity after intercourse) should break his fast that day." Marwan said: "I swear by Allah, O Abdul-Rahman, you must go to Ummul Mu'mineen Aishah and Umm Salamah and ask them about this." So Abdul-Rahman went and I went with him until we entered upon Aishah. Abdul-Rahman greeted her and said: "O Mother of the Believers, we were with Marwan and he mentioned to him what Abu Hurairah said: 'Whoever wakes up in a state of janabah should break his fast that day.' Aishah said: 'I bear witness to the Messenger of Allah ﷺ that he used to wake up in a state of janabah due to intercourse, not due to a wet dream, and he would fast that day.' Then we left and went to Umm Salamah and asked her. She said the same as Aishah. Then we went to Marwan and Abdul-Rahman told him what they had said. Marwan said: 'I swear by Allah, O Abu Muhammad, you must ride my she-camel, for it is at the gate. Go to Abu Hurairah, for he is in his land in Al-'Aqiq, and inform him of that.' Abu Bakr said: Abdul-Rahman rode (the she-camel) and I rode with him until we reached Abu Hurairah. Abdul-Rahman spoke with him for a while, then he mentioned it to him. Abu Hurairah said: 'I have no knowledge about it, I was only told this by a narrator.' Abu Abdullah (Imam Ahmad) said: Abu Qilabah narrated from Abdul-Rahman bin Al-Harith that he informed Abu Hurairah about the statement of Aishah and Umm Salamah. Abu Hurairah said: 'That is what I thought, but it was not allowed for anyone to do it except him.'"

[Machine] Hudhayfah said: Whoever wakes up in a state of major impurity (janabah), he should fast that day. Marwan then said: I swear by Allah, O Abdur-Rahman, you must go to the Mothers of the Believers, Aisha and Umm Salamah, and ask them about that. Abu Bakr said: So Abdur-Rahman went and I went with him until we entered upon Aisha. Abdur-Rahman greeted her and said: O Mother of the Believers, we were with Marwan and it was mentioned to him that Abu Hurayrah said: Whoever wakes up in a state of major impurity (janabah), he should fast that day. Aisha said: It is not as Abu Hurayrah said. O Abdur-Rahman, do you desire something that the Messenger of Allah ﷺ did? Abdur-Rahman said: No, by Allah. Aisha said: Then I bear witness to the Messenger of Allah ﷺ that he would wake up in a state of major impurity (janabah) from sexual intercourse, other than a wet dream, and then he would fast that day. Aisha said: Afterwards we left until we entered upon Umm Salamah. Abdur-Rahman asked her about that, and she said the same thing as Aisha. Then we left until we came to Marwan, and Abdur-Rahman said to him: What did they say? Marwan said: I swear by you, O Abu Muhammad, that you must ride my mount at the door (of the Masjid), and go to Abu Hurayrah and inform him of that. So Abdur-Rahman rode, and I rode with him, until we came to Abu Hurayrah and Abdur-Rahman spoke to him for a while. Then he mentioned that to him, and Abu Hurayrah said: I have no knowledge of that. Only one informant told me
