وَ رَوَى عَمْرُو بْنُ شِمْرٍ عَنْ جَابِرٍ عَنْ أَبِي جَعْفَرٍ عَلَيْهِ اَلسَّلاَمُ: قَالَ "اِحْتَجَمَ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ حَجَمَهُ مَوْلًى لِبَنِي بَيَاضَةَ وَ أَعْطَاهُ وَ لَوْ كَانَ حَرَاماً مَا أَعْطَاهُ فَلَمَّا فَرَغَ قَالَ لَهُ رَسُولُ اَللَّهِ صَلَّى اَللَّهُ عَلَيْهِ وَ آلِهِ "أَيْنَ اَلدَّمُ" قَالَ شَرِبْتُهُ يَا رَسُولَ اَللَّهِ فَقَالَ "مَا كَانَ يَنْبَغِي لَكَ أَنْ تَفْعَلَهُ وَ قَدْ جَعَلَهُ اَللَّهُ لَكَ حِجَاباً مِنَ اَلنَّارِ" ".
Imam Abu Ja'far Imam Muhammad ibn Ali Al-Baqir (a.s), narrated through Jabir from Amr ibn Shimr: "The Messenger of Allah (swt), peace and blessings be upon him and his family, underwent cupping. A servant from the tribe of Banu Bayadah performed the cupping, and the Prophet (saws) gave him payment. If it were prohibited, he would not have given him payment. When the procedure was completed, the Messenger of Allah (swt), peace and blessings be upon him and his family, asked him: 'Where is the blood?' The servant replied: 'I drank it, O Messenger of Allah (swt).' The Prophet said: 'You should not have done that, but Allah (swt) has made it a barrier for you against the Fire.'"
