"The Messenger of Allah married Maimunah while he was Halal, and he stayed with her while he was Halal, and I was the messenger between the two of them." (Using translation from Tirmidhī 841)
«أَنَّ رَسُولَ اللهِ ﷺ تَزَوَّجَ مَيْمُونَةَ حَلَالًا وَبَنَى بِهَا حَلَالًا وَكُنْتُ الرَّسُولَ بَيْنَهُمَا»
