One may begin to fast even after having intimacy

muslim:1109a – [Chain 1] Muḥammad b. Ḥātim > Yaḥyá b. Saʿīd > Ibn Jurayj [Chain 2] Muḥammad b. Rāfiʿ > ʿAbd al-Razzāq b. Hammām > Ibn Jurayj > ʿAbd al-Malik b. Abū Bakr b. ʿAbd al-Raḥman > Abū Bakr > Abū Hurayrah

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.  

مسلم:١١٠٩a – حَدَّثَنِي مُحَمَّدُ بْنُ حَاتِمٍ حَدَّثَنَا يَحْيَى بْنُ سَعِيدٍ عَنِ ابْنِ جُرَيْجٍ ح وَحَدَّثَنِي مُحَمَّدُ بْنُ رَافِعٍ وَاللَّفْظُ لَهُ حَدَّثَنَا عَبْدُ الرَّزَّاقِ بْنُ هَمَّامٍ أَخْبَرَنَا ابْنُ جُرَيْجٍ أَخْبَرَنِي عَبْدُ الْمَلِكِ بْنُ أَبِي بَكْرِ بْنِ عَبْدِ الرَّحْمَنِ عَنْ أَبِي بَكْرٍ قَالَ سَمِعْتُ أَبَا هُرَيْرَةَ ؓ يَقُصُّ يَقُولُ فِي قَصَصِهِ مَنْ أَدْرَكَهُ الْفَجْرُ جُنُبًا فَلاَ يَصُمْ فَذَكَرْتُ ذَلِكَ لِعَبْدِ الرَّحْمَنِ بْنِ الْحَارِثِ لأَبِيهِ فَأَنْكَرَ ذَلِكَ فَانْطَلَقَ عَبْدُ الرَّحْمَنِ وَانْطَلَقْتُ مَعَهُ حَتَّى دَخَلْنَا عَلَى عَائِشَةَ وَأُمِّ سَلَمَةَ ؓ فَسَأَلَهُمَا عَبْدُ الرَّحْمَنِ عَنْ ذَلِكَ قَالَ فَكِلْتَاهُمَا قَالَتْ

كَانَ النَّبِيُّ ﷺ يُصْبِحُ جُنُبًا مِنْ غَيْرِ حُلُمٍ ثُمَّ يَصُومُ  

قَالَ فَانْطَلَقْنَا حَتَّى دَخَلْنَا عَلَى مَرْوَانَ فَذَكَرَ ذَلِكَ لَهُ عَبْدُ الرَّحْمَنِ فَقَالَ مَرْوَانُ عَزَمْتُ عَلَيْكَ إِلاَّ مَا ذَهَبْتَ إِلَى أَبِي هُرَيْرَةَ فَرَدَدْتَ عَلَيْهِ مَا يَقُولُ قَالَ فَجِئْنَا أَبَا هُرَيْرَةَ وَأَبُو بَكْرٍ حَاضِرُ ذَلِكَ كُلِّهِ قَالَ فَذَكَرَ لَهُ عَبْدُ الرَّحْمَنِ فَقَالَ أَبُو هُرَيْرَةَ أَهُمَا قَالَتَاهُ لَكَ قَالَ نَعَمْ قَالَ هُمَا أَعْلَمُ ثُمَّ رَدَّ أَبُو هُرَيْرَةَ مَا كَانَ يَقُولُ فِي ذَلِكَ إِلَى الْفَضْلِ بْنِ الْعَبَّاسِ فَقَالَ أَبُو هُرَيْرَةَ سَمِعْتُ ذَلِكَ مِنَ الْفَضْلِ وَلَمْ أَسْمَعْهُ مِنَ النَّبِيِّ ﷺ قَالَ فَرَجَعَ أَبُو هُرَيْرَةَ عَمَّا كَانَ يَقُولُ فِي ذَلِكَ قُلْتُ لِعَبْدِ الْمَلِكِ أَقَالَتَا فِي رَمَضَانَ قَالَ كَذَلِكَ كَانَ يُصْبِحُ جُنُبًا مِنْ غَيْرِ حُلُمٍ ثُمَّ يَصُومُ

[Machine] "Abdullah al-Hafiz informed Abu Abdullah al-Shaybani, who narrated from Ibrahim ibn Abi Talib, who narrated from Muhammad ibn Rafi', who narrated from Abdul Razzaq, who narrated from Ibn Jurayj, who reported from Abdul Malik ibn Abi Bakr ibn Abdul Rahman, who narrated from his father Abu Bakr, meaning his father, who said: I heard Abu Huraira saying about his stories, 'Whoever experiences sexual emission before dawn should not fast.' Then I mentioned this to Abdul Rahman ibn Al-Harith, his father, and he denied it. So Abdul Rahman went and I went with him until we entered upon Aisha and Umm Salama. Abdul Rahman asked them about this matter, and they both said, 'The Messenger of Allah ﷺ would wake up in a state of junub (ritual impurity after sexual intercourse) sometimes without dreaming, and then he would fast.' So we left until we reached Marwan, and Abdul Rahman mentioned this to him. Marwan said, 'I wanted to scold you except that you went to Abu Huraira and mentioned to him what he said.' So we went to Abu Huraira, and Abu Bakr was present throughout all of this. Abdul Rahman mentioned this to him, and Abu Huraira said, 'I heard this from Fadl ibn Abbas, and I did not hear it from the Prophet ﷺ .' Then Abu Huraira abandoned what he used to say about this matter. I said to Abdul Malik, 'Did they say this about Ramadan?' He said, 'Yes, he would sometimes wake up in a state of junub without dreaming, and then he would fast.'"
