Ibn ‘Awn told us, that Raja" bin Haiwah said:

Ya"la bin "Uqbah consummated his marriage in Ramadan, and the next morning he was junub. He met Abu Hurairah and asked him, and he said: Break your fast. He said: Can I not fast this day, then make it up later on? [Abu Hurairah] said: Break your fast. So. [Ya"la] went to Marwan and told him, and he sent Abu Bakr bin ‘Abdur -Rahman bin al-Harith to Umm al-Mu"mineen to ask her, and she said: The Prophet (ﷺ) would wake up junub among us, not from a wet dream, and he would fast. So he went back to Marwan and told him, and he said: Go and tell Abu Hurairah about it. He said: He is my neighbour [i.e., he did not want to upset him]. But [Marwan] said: I insist that you go and tell him. So he met him and told him, and [Abu Hurairah] said: I did not hear it from the Prophet (ﷺ) ; rather al-Fadl bin ‘Abbas told me about it. He said: After that I met Raja" and said: Who told you the hadeeth about Ya"la? He said: He told it to me.
