Tahdhīb al-Aḥkām|Volume 1|Book 1|Chapter 12
فَأَمَّا مَا رَوَاهُ مُعَاوِيَةُ بْنُ حُكَيْمٍ عَنِ اِبْنِ اَلْمُغِيرَةِ عَنْ مُثَنَّى بْنِ عَبْدِ اَلسَّلاَمِ عَنْ أَبِي عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ قَالَ: قُلْتُ لَهُ إِنِّي حَكَكْتُ جِلْدِي فَخَرَجَ مِنْهُ دَمٌ فَقَالَ« إِنِ اِجْتَمَعَ قَدْرَ حِمَّصَةٍ فَاغْسِلْهُ وَ إِلاَّ فَلاَ».
Mu'awiyah ibn Hakim narrated from Ibn Al-Mughira, from Muthanna ibn Abd Al-Salam, from Abu Abdullah عليه السلام. He said:
I said to Imam عليه السلام: "I scratched my skin, and blood came out." Imam عليه السلام said: "If it gathers to the size of a lentil (hummus seed), then wash it. Otherwise, you do not need to wash it."
