Should one observing fast kiss (his wife)? The Messenger of Allah ﷺ said to him: Ask her (Umm Salama). She informed him that the Messenger of Allah ﷺ did that, where upon he said: Messenger of Allah, Allah pardoned thee all thy sins, the previous and the later ones. Upon this the Messenger of Allah ﷺ ) said: By Allah, I am the most God conscious among you and I fear Him most among you. (Using translation from Muslim 1108)
رَسُولَ اللهِ ﷺ أَيُقَبِّلُ الصَّائِمُ؟ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ سَلْ هَذِهِ لِأُمِّ سَلَمَةَ فَأَخْبَرَتْهُ أَنَّ رَسُولَ اللهِ ﷺ يَصْنَعُ ذَلِكَ فَقَالَ يَا رَسُولَ اللهِ قَدْ غَفَرَ اللهُ لَكَ مَا تَقَدَّمَ مِنْ ذَنْبِكَ وَمَا تَأَخَّرَ فَقَالَ لَهُ رَسُولُ اللهِ ﷺ أَمَا وَاللهِ إِنِّي لَأَتْقَاكُمْ لِلَّهِ وَأَخْشَاكُمْ لَهُ
