[Machine] Hamzah ibn Abdul-Muttalib was fighting on the day of Uhud, in front of the Messenger of Allah ﷺ, and he would say, "I am the Lion of Allah, as agreed upon by the two Shaykhs, and they did not invalidate it." (authentic)
كَانَ حَمْزَةُ بْنُ عَبْدِ الْمُطَّلِبِ يُقَاتِلُ يَوْمَ أُحُدٍ بَيْنَ يَدَيْ رَسُولِ اللَّهِ ﷺ وَيَقُولُ أَنَا أَسَدُ اللَّهِ «صَحِيحٌ عَلَى شَرْطِ الشَّيْخَيْنِ وَلَمْ يُخَرِّجَاهُ» صحيح
