Yahya related to me from Malik from Yahya ibn Said that Atika bint Zayd ibn Amr ibn Nufayl, the wife of Umar ibn al-Khattab, used to kiss Umar ibn al-Khattab's head while he was fasting, and he did not tell her not to.  

مالك:١٨-١٦ – وَحَدَّثَنِي عَنْ مَالِكٍ عَنْ يَحْيَى بْنِ سَعِيدٍ

أَنَّ عَاتِكَةَ ابْنَةَ زَيْدِ بْنِ عَمْرِو بْنِ نُفَيْلٍ امْرَأَةَ عُمَرَ بْنِ الْخَطَّابِ كَانَتْ تُقَبِّلُ رَأْسَ عُمَرَ بْنِ الْخَطَّابِ وَهُوَ صَائِمٌ فَلاَ يَنْهَاهَا

السيوطي:٢-١٦٨٤b –

"عن يَحْيى بنِ سعيدٍ أنَّ عاتكةَ بِنْت زَيْدِ بن عَمْرو بن نفيلٍ امرأة عُمَرَ ابْنِ الْخَطَّابِ كَانَتْ تُقبِّلُ رأَسَ عُمَرَ وَهُوَ صَائِم وَلَا يَنْهَاهَا".  

مالك، وابن سعد، وأورده ابن سعد أيضا عن يحيى بن سعيد عن أَبى بكر بن محمد بن عمر، وابن جرير عن عبيد اللَّه بن عبد اللَّه بن عمر أن عاتكة امرأة عمر قَبَّلَتْهُ، وهُوَ صائِمٌ فَلَمْ يَنْهَهَا
