Shama'il al-Muhammadiya 16

Jaabir bin Samurah (may Allah be pleased with him) reports that:
"I saw the Seal of Prophethood of Messenger of Allah ﷺ between his two shoulders, which was like a red tumor (protruding flesh), the size of which was like that of a pigeon's egg"

حَدَّثَنَا سَعِيدُ بْنُ يَعْقُوبَ الطَّالْقَانِيُّ، قَالَ: حدَّثَنَا أَيُّوبُ بْنُ جَابِرٍ، عَنْ سِمَاكِ بْنِ حَرْبٍ، عَنْ جَابِرِ بْنِ سَمُرَةَ، قَالَ: رَأَيْتُ الْخَاتَمَ بَيْنَ كَتِفَيْ رَسُولِ اللهِ ﷺ، غُدَّةً حَمْرَاءَ، مِثْلَ بَيْضَةِ الْحَمَامَةِ.
