One who is better than I informed me, that Messenger of Allah ﷺ said to ʿAmmar as he was digging the ditch (on the ocassion of the Battle of the Ditch) wiping over his head: O son of Summayya, you will be involved in trouble and a group of the rebels would kill you. (Using translation from Muslim 2915a)
أَنَّ رَسُولَ اللهِ ﷺ قَالَ لِعَمَّارٍ حِينَ جَعَلَ يَحْفِرُ الْخَنْدَقَ وَجَعَلَ يَمْسَحُ رَأْسَهُ وَيَقُولُ بُؤْسَ ابْنِ سُمَيَّةَ تَقْتُلُكَ الْفِئَةُ الْبَاغِيَةُ
