Does passing wind during ghusl for janabah invalidate the ghusl?

The emission of gas (wind) nullifies ablution (Wudu'), not the ritual bath (Ghusl). Therefore, whoever emits gas during Ghusl should complete their Ghusl and then perform Wudu' afterward. Ghusl performed for a major impurity (hadath akbar) suffices for Wudu'; hence, Wudu' is not obligatory after it unless a nullifier of Wudu' occurs during or after the Ghusl. It is important to note the rinsing of the mouth (madmadah) and nose (istinshaq) in both Wudu' and Ghusl.
