عَنْ حَفْصَةَ بِنْتِ عُمَرَ رَضِيَ اللَّهُ عَنْهَا أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ كَانَ يُقَبِّلُ وَهُوَ صَائِمٌ
It is narrated from Sayyidah Hafsah bint Umar (may Allah be pleased with her) that the Messenger of Allah (peace and blessings be upon him) used to kiss while in the state of fasting.
