عَنْ أَنَسٍ رَضِيَ اللَّهُ عَنْهُ قَالَ كَوَانِي أَبُو طَلْحَةَ وَرَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بَيْنَ أَظْهُرِنَا فَمَا نُهِيتُ عَنْهُ
Sayyiduna Anas (may Allah be pleased with him) narrates that Sayyiduna Abu Talhah (may Allah be pleased with him) cauterized me as a treatment, while the Messenger of Allah (peace and blessings be upon him) was present among us, and I was not prohibited from this.
