A man came from Najran to the Messenger of Allah [SAW]. He was wearing a gold ring, and the Messenger of Allah [SAW] turned away from him, and said: "You have come to me with a coal of fire on your hand." (Using translation from Nasāʾī 5188)
أَنَّ رَجُلًا قَدِمَ مِنْ نَجْرَانَ إِلَى رَسُولِ اللهِ ﷺ وَعَلَيْهِ خَاتَمٌ مِنْ ذَهَبٍ فَأَعْرَضَ عَنْهُ رَسُولُ اللهِ ﷺ فَقَالَ «إِنَّكَ جِئْتَنِي وَفِي يَدِكَ جَمْرَةٌ مِنْ نَارٍ»
