عَنْ عَائِشَةَ رَضِيَ اللَّهُ عَنْهَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ إِذَا اغْتَسَلَ مِنَ الْجَنَابَةِ تَمَضْمَضَ وَاسْتَنْشَقَ
It is narrated from Sayyida Aisha (may Allah be pleased with her) that when the Messenger of Allah (peace and blessings be upon him) performed the ritual bath of janabah, he would rinse his mouth and draw water into his nose.
