[Machine] "I swear by your well-being, I would lay down my life for you, until I reached the point where I saw the Messenger of Allah ﷺ kissing it. Then, he uncovered his belly and kissed his navel. Even if it was part of the 'awrah (private parts), he would still uncover it."  

ابن حبّان:٦٩٦٥ – أَخْبَرَنَا الْحَسَنُ بْنُ سُفْيَانَ حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ عَنِ ابْنِ عَوْنٍ عَنْ عُمَيْرِ بْنِ إِسْحَاقَ قَالَ كُنْتُ أَمْشِي مَعَ الْحَسَنِ بْنِ عَلِيٍّ فِي طُرُقِ الْمَدِينَةِ فَلَقِينَا أَبَا هُرَيْرَةَ فَقَالَ لِلْحَسَنِ «اكْشِفْ لِي

عَنْ بَطْنِكَ جُعِلْتُ فِدَاكَ حَتَّى أُقَبِّلَ حَيْثُ رَأَيْتُ رَسُولَ اللَّهِ ﷺ يُقَبِّلُهُ قَالَ فَكَشَفَ عَنْ بَطْنِهِ فَقَبَّلَ سُرَّتَهُ وَلَوْ كَانَتْ مِنَ الْعَوْرَةِ مَا كَشَفَهَا
