That was the part of Satan in thee. And then he washed it with the water of Zamzam in a golden basin and then it was joined together and restored to it place. The boys came running to his mother, i. e. his nurse, and said: Verily Muhammad has been murdered. They all rushed toward him (and found him all right) His color was changed, Anas said. I myself saw the marks of needle on his breast.  

أَنَّ رَسُولَ اللَّهِ ﷺ أَتَاهُ جِبْرِيلُ ﷺ 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 لأَمَهُ ثُمَّ أَعَادَهُ فِي مَكَانِهِ وَجَاءَ الْغِلْمَانُ يَسْعَوْنَ إِلَى أُمِّهِ يَعْنِي ظِئْرَهُ فَقَالُوا إِنَّ مُحَمَّدًا قَدْ قُتِلَ فَاسْتَقْبَلُوهُ وَهُوَ مُنْتَقَعُ اللَّوْنِ قَالَ أَنَسٌ وَقَدْ كُنْتُ أَرَى أَثَرَ ذَلِكَ الْمِخْيَطِ فِي صَدْرِهِ  

[Machine] The Prophet Muhammad ﷺ was playing with some young boys when the Angel Gabriel ﷺ came to him and grabbed him, causing him to fall down and his chest to be split open. Gabriel then removed a clot from his heart and said, "This is the Shaytan's portion from you." He then washed it in a golden basin filled with Zamzam water and placed it back in its original place. The young boys ran to their mother and said, "Muhammad has been killed!" They rushed to him and found him pale in color. Anas said, "I saw the mark of the stitches on his chest, and perhaps Hammad said, 'The Messenger of Allah ﷺ was visited by someone.'"  

أَنَّ رَسُولَ اللهِ ﷺ أَتَاهُ جِبْرِيلُ عَلَيْهِ السَّلَامُ وَهُوَ يَلْعَبُ مَعَ الْغِلْمَانِ فَأَخَذَهُ فَصَرَعَهُ فَشَقَّ عَنْ قَلْبِهِ فَاسْتَخْرَجَ مِنْهُ عَلَقَةً فَقَالَ هَذَا حَظُّ الشَّيْطَانِ مِنْكَ ثُمَّ غَسَلَهُ فِي طَسْتٍ مِنْ ذَهَبٍ بِمَاءِ زَمْزَمَ ثُمَّ لَأَمَهُ وَأَعَادَهُ فِي مَكَانِهِ وَجَاءَ الْغِلْمَانُ يَسْعَوْنَ إِلَى أُمِّهِ يَعْنِي ظِئْرِهِ فَقَالُوا إِنَّ مُحَمَّدًا قَدْ قُتِلَ فَاسْتَقْبَلُوهُ وَهُوَ مُنْتَقِعُ اللَّوْنِ قَالَ لِي أَنَسٌ فَكُنْتُ أَرَى أَثَرَ الْمِخْيَطِ فِي صَدْرِهِ وَرُبَّمَا قَالَ حَمَّادٌ إِنَّ رَسُولَ اللهِ ﷺ أَتَاهُ آتٍ  

That was the part of Satan in thee. And then he washed it with the water of Zamzam in a golden basin and then it was joined together and restored to it place. The boys came running to his mother, i. e. his nurse, and said: Verily Muhammad has been murdered. They all rushed toward him (and found him all right) His color was changed, Anas said. I myself saw the marks of needle on his breast. (Using translation from Muslim 162c)  

أَنَّ رَسُولَ اللهِ ﷺ أَتَاهُ جِبْرِيلُ وَهُوَ يَلْعَبُ مَعَ الْغِلْمَانِ فَأَخَذَهُ فَصَرَعَهُ وَشَقَّ عَنْ قَلْبِهِ فَاسْتَخْرَجَ الْقَلْبَ ثُمَّ شَقَّ الْقَلْبَ فَاسْتَخْرَجَ مِنْهُ عَلَقَةً فَقَالَ هَذِهِ حَظُّ الشَّيْطَانِ مِنْكَ قَالَ فَغَسَلَهُ فِي طَسْتٍ مِنْ ذَهَبٍ بِمَاءِ زَمْزَمَ ثُمَّ لَأَمَهُ ثُمَّ أَعَادَهُ فِي مَكَانِهِ قَالَ وَجَاءَ الْغِلْمَانُ يَسْعَوْنَ إِلَى أُمِّهِ يَعْنِي ظِئْرَهُ فَقَالُوا إِنَّ مُحَمَّدًا قَدْ قُتِلَ قَالَ فَاسْتَقْبَلُوهُ وَهُوَ مُنْتَقِعُ اللَّوْنِ قَالَ أَنَسٌ وَكُنْتُ أَرَى أَثَرَ الْمِخْيَطِ فِي صَدْرِهِ  

[Machine] The Messenger of Allah ﷺ used to play with the children. A man came and embraced him, and then ripped open his stomach, taking out a leech from it. He threw it away and said, "This is your portion from Satan." Then he washed it in a cup made of gold with Zamzam water. After that, he returned to his mother while the children followed him, saying, "Muhammad has been killed, Muhammad has been killed." The Messenger of Allah ﷺ faced them, and his face had turned pale. Anas said, "We used to see the effect of the leech on his chest."  

أَنَّ رَسُولَ اللهِ ﷺ كَانَ يَلْعَبُ مَعَ الصِّبْيَانِ فَأَتَاهُ آتٍ فَأَخَذَهُ فَشَقَّ بَطْنَهُ فَاسْتَخْرَجَ مِنْهُ عَلَقَةً فَرَمَى بِهَا وَقَالَ هَذِهِ نَصِيبُ الشَّيْطَانِ مِنْكَ ثُمَّ غَسَلَهُ فِي طَسْتٍ مِنْ ذَهَبٍ مِنْ مَاءِ زَمْزَمَ ثُمَّ لَأَمَهُ فَأَقْبَلَ الصِّبْيَانُ إِلَى ظِئْرِهِ قُتِلَ مُحَمَّدٌ قُتِلَ مُحَمَّدٌ فَاسْتَقْبَلَتْ رَسُولَ اللهِ ﷺ وَقَدِ انْتَقَعَ لَوْنُهُ قَالَ أَنَسٌ فَلَقَدْ كُنَّا نَرَى أَثَرَ الْمَخِيطِ فِي صَدْرِهِ  

[Machine] That the Messenger of Allah ﷺ was visited by Gabriel while he was playing with some children. Gabriel held him and pressed him until he was short of breath and then removed a clot from his heart, saying, "This is the share of Satan from you." He then washed it in a golden basin with Zamzam water and put it back in its place. Anas said, "Then the boys came running to their mother meaning his heart, and they said, 'Verily Muhammad has been murdered.' His heart approached them while he was turning pale." Anas said, "We could see the marks of stitches on his chest." The narration has been reported as authentic with a correct chain of narration, and it has also been narrated by Umar ibn Al-Khattab and Ali ibn Abi Talib, 'Nothing can overcome two easiness.'"

[Machine] "that the Messenger of Allah ﷺ was approached by Gabriel while he was playing with children, and Gabriel took hold of him and pressed him until his heart was split open, and then he extracted a blood clot from it, saying: 'This is the portion of Satan from you.'"  

«أَنَّ رَسُولَ اللَّهِ ﷺ أَتَاهُ جِبْرِيلُ عَلَيْهِ السَّلَامُ وَهُوَ يَلْعَبُ مَعَ الصِّبْيَانِ فَأَخَذَهُ فَصَرَعَهُ فَشَقَّ قَلْبَهُ فَاسْتَخْرَجَ مِنْهُ عَلَقَةً فَقَالَ هَذَا حَظُّ الشَّيْطَانِ مِنْكَ ثُمَّ غَسَلَهُ فِي طَسْتٍ مِنْ ذَهَبٍ بِمَاءِ زَمْزَمَ ثُمَّ أَعَادَهُ فِي مَكَانِهِ فَجَاءَهُ الْغِلْمَانُ يَسْعَوْنَ إِلَى أُمِّهِ يَعْنِي ظِئْرَهُ فَقَالَ إِنَّ مُحَمَّدًا قَدْ قُتِلَ فَاسْتَقْبَلُوهُ مُنْتَقِعَ اللَّوْنِ»  

"عَنْ أنَسٍ: أَنَّ رَسُولَ اللهِ ﷺ أتَاهُ جِبْرِيلُ وَهُوَ يَلعَبُ مَعَ الغِلمَانِ، فَأخذَهُ فَصَرَعَهُ، فَشَقَّ عَنْ قَلبِهِ، فَاسْتَخْرَجَ القَلْبَ، فَاسْتَخْرَجَ مِنْهُ عَلَقَةً، فَقَالَ: هَذَا حَظُّ الشَّيْطَانِ منْكَ، ثُمَّ غَسَلَهُ فِى طَسْتٍ مِنْ ذَهَب بِمَاءِ زَمْزَمَ، ثُمَّ لأمَهُ (*)، ثُمَّ أعَادَهُ فِى مَكَانِهِ، وَجَاءَ الغلمَانُ يَسْعَونَ إِلَى أُمِّهِ (يعنى: ظِئْرَهُ) فَقَالُوا: إِنَّ مُحَمَّدًا قَدْ قُتِلَ، فَاسْتَقْبَلُوهُ وَهُوَ مُنْتَقَعُ اللَّوْنِ، قَالَ أنَسٌ: وَقَدْ كُنتُ أرَى أثَرَ ذَلكَ المخْيَط فِى صَدْرِه".
