The fuqaha’ differed as to whether ghusl is required if maniy comes out after doing ghusl.
The correct view is that of the Hanbalis, which is that if it comes out without feelings of desire, then ghusl is not required, because it is left over from the first maniy. If it does come out with feelings of desire, then ghusl is required because it is different from the first maniy and was emitted with new feelings of desire.
Ibn Qudaamah (may Allaah have mercy on him) said: If a person has a wet dream or has intercourse and ejaculates, then does ghusl, then some maniy comes out of him, the well known view that was narrated from Ahmad is that he does not have to do ghusl. Al-Khallaal said: There are mutawaatir reports from Abu ‘Abd-Allaah (i.e., Imam Ahmad) which say that he only has to do wudoo’. That was narrated from ‘Ali, Ibn ‘Abbaas, ‘Ata’, al-Zuhri, Maalik, al-Layth, al-Thawri and Ishaaq. Sa’eed ibn Jubayr said: He does not have to do ghusl unless there is desire. End quote from al-Mughni (1/128).
See al-Insaaf (1/232) and Kashshaaf al-Qinaa’ (1/141).
The evidence for that is:
1 – Sa’eed narrated from Ibn ‘Abbaas (may Allaah be pleased with him) that he was asked about the one who is junub and something comes out of him after doing ghusl. He said: He should do wudoo’. Imam Ahmad narrated something similar from ‘Ali.
2 – Because it is one maniy so only one ghusl is required, just as if it was emitted in one go.
3 – Because that which comes out without desire is more akin to that which comes out because of cold. This is what Imam Ahmad cited when he said: Because the desire is past; rather it is minor impurity for which I hope that wudoo’ will suffice. End quote from Kashf al-Qinaa’ (1/142).
Shaykh Ibn ‘Uthaymeen (may Allaah have mercy on him) said: The words “If it comes out after that he should not repeat it” mean: if he did ghusl for that which was already emitted, then it comes out when he moves, then he should not repeat ghusl. The evidence for that is:
1 – The reason is one and the same, so there is no need for two ghusls.
2 – It came out after that without feelings of pleasure, and ghusl is not required unless it comes out with feelings of pleasure.
But if maniy comes out again because of (renewed) desire and gushes out, then he must do ghusl again because this is a new reason. End quote from al-Sharh al-Mumti’ (1/281).
Shaykh Ibn ‘Uthaymeen was asked about this fluid that comes out after doing ghusl for janaabah. He replied:
As for this fluid that comes out after doing ghusl for janaabah, if there is no new feeling of desire that caused it to be emitted, then it is the remainder of that for which the first ghusl was done, so he does not have to do ghusl for that. Rather he has to wash off whatever of it has got onto him, and he has to do wudoo’ only. End quote. Fataawa Ibn ‘Uthaymeen (11/222).
This was the view favoured by the scholars of the Standing Committee when they said: If a person has done ghusl for janaabah then some maniy comes out of him after doing ghusl, it is sufficient for him to wash it and he does not have to repeat ghusl, rather he has to do instinja’ (wash his private part) and do wudoo’. End quote.
