وعنها قَالَت: مَا كَانَ يَكُونَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قُرْحَةٌ وَلَا نَكْبَةٌ إِلَّا أَمَرَنِي أَنْ أَضَعَ عَلَيْهَا الْحِنَّاء. رَوَاهُ التِّرْمِذِيّ

She said that God’s messenger never had a wound or a bleeding foot* without ordering her to put henna on it. Tirmidhi transmitted it. * Nakba is used. It means an injury to the foot caused by a stone which produce bleeding.
