Sahih Muslim Book - 1, Hadith - 413

حَدَّثَنَا شَيْبَانُ بْنُ فَرُّوخَ حَدَّثَنَا حَمَّادُ بْنُ سَلَمَةَ حَدَّثَنَا ثَابِتٌ الْبُنَانِيُّ عَنْ أَنَسِ بْنِ مَالِكٍ أَنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ أَتَاهُ جِبْرِيلُ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَهُوَ يَلْعَبُ مَعَ الْغِلْمَانِ فَأَخَذَهُ فَصَرَعَهُ فَشَقَّ عَنْ قَلْبِهِ فَاسْتَخْرَجَ الْقَلْبَ فَاسْتَخْرَجَ مِنْهُ عَلَقَةً فَقَالَ هَذَا حَظُّ الشَّيْطَانِ مِنْكَ ثُمَّ غَسَلَهُ فِي طَسْتٍ مِنْ ذَهَبٍ بِمَاءِ زَمْزَمَ ثُمَّ لَأَمَهُ ثُمَّ أَعَادَهُ فِي مَكَانِهِ وَجَاءَ الْغِلْمَانُ يَسْعَوْنَ إِلَى أُمِّهِ يَعْنِي ظِئْرَهُ فَقَالُوا: إِنَّ مُحَمَّدًا قَدْ قُتِلَ فَاسْتَقْبَلُوهُ وَهُوَ مُنْتَقِعُ اللَّوْنِ قَالَ أَنَسٌ وَقَدْ كُنْتُ أَرْئِي أَثَرَ ذَلِكَ الْمِخْيَطِ فِي صَدْرِهِ.

It was narrated from Anas bin Malik that Jibril, came to the Messenger of Allah (s.a.w) (when he was a boy and living with Halima, the wet nurse) while he was playing with the other boys. He took hold of him and threw him to the ground, then he opened his chest and took out his heart, from which he took a clot of blood and said: "This was the Shaitan 's share of you." Then he washed it in a vessel of gold that was filled with Zamzam. Then he put it back together and returned it to its place. The boys went running to his mother - meaning his wet nurse - and said: "Muhammad has been killed!" They went to him and his color had changed. Anas said: "I used to see the mark of that stitching on his chest."
