Is the ruling on offering Salah

Q: Is it permissible to perform Salah with the Wudu' (ablution) made before sleeping in case of Janabah (major ritual impurity related to sexual discharge)? It is claimed that this is an act of Sunnah.

A: It is not permitted for whoever makes Wudu' due to Janabah before going to sleep to perform Salah, obligatory or supererogatory. He should perform Ghusl (full ritual bath) following major ritual impurity before praying.May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
