He said: "I said to her: 'Tell me your Hadith.' She said: 'I got Khul' from my husband, then I came to 'Uthman and asked him: "What waiting period do I have to observe?" He said: "You do not have to observe any waiting period, unless you had intercourse with him recently, in which case you should stay with him until you have menstruated." In that he was following the ruling of the Messenger of Allah ﷺ concerning Maryam Maghaliyyah, who was married to Thabit bin Qais and she got Khul' from him.' " (Using translation from Ibn Mājah 2058)
اخْتَلَعْتُ مِنْ زَوْجِي ثُمَّ جِئْتُ عُثْمَانَ فَسَأَلْتُهُ مَاذَا عَلَيَّ مِنَ الْعِدَّةِ؟ فَقَالَ لَا عِدَّةَ عَلَيْكِ إِلَّا أَنْ يَكُونَ حَدِيثَ عَهْدٍ بِكِ فَتَمْكُثِينَ حَتَّى تَحِيضِي حَيْضَةً قَالَتْ وَإِنَّمَا يُتْبَعُ فِي ذَلِكَ قَضَاءُ رَسُولِ اللهِ ﷺ فِي مَرْيَمَ الْمَغَالِيَّةِ كَانَتْ تَحْتَ ثَابِتِ بْنِ قَيْسِ بْنِ شَمَّاسٍ فَاخْتَلَعَتْ مِنْهُ
