Prophecy of the martyrdom of Ammar b. Yasir by the rebellious group

that Ibn Abbas told him and Ali b. Abdullah to go to Abu Sa'id and listen to some of his narrations; So they both went and Abu Sa'id and his brother were irrigating a garden belonging to them. When he saw us, he came up to and sat down with his legs drawn up and wrapped in his garment and said: ˹During the construction of the mosque of the Prophet˺ we carried the adobe of the masjid, one brick at a time while Ammar used to carry two at a time.

The Prophet ﷺ passed by Ammar and removed the dust off his head and said, "May Allah have mercy on Ammar, he will be killed by the rebellious group. Ammar will invite them to Allah and they will invite him to the Hellfire."  

أَنَّ ابْنَ عَبَّاسٍ قَالَ لَهُ وَلِعَلِيِّ بْنِ عَبْدِ اللَّهِ ائْتِيَا أَبَا سَعِيدٍ فَاسْمَعَا مِنْ حَدِيثِهِ فَأَتَيْنَاهُ وَهُوَ وَأَخُوهُ فِي حَائِطٍ لَهُمَا يَسْقِيَانِهِ فَلَمَّا رَآنَا جَاءَ فَاحْتَبَى وَجَلَسَ فَقَالَ كُنَّا نَنْقُلُ لَبِنَ الْمَسْجِدِ لَبِنَةً لَبِنَةً وَكَانَ عَمَّارٌ يَنْقُلُ لَبِنَتَيْنِ لَبِنَتَيْنِ

فَمَرَّ بِهِ النَّبِيُّ ﷺ وَمَسَحَ عَنْ رَأْسِهِ الْغُبَارَ وَقَالَ وَيْحَ عَمَّارٍ تَقْتُلُهُ الْفِئَةُ الْبَاغِيَةُ عَمَّارٌ يَدْعُوهُمْ إِلَى اللَّهِ وَيَدْعُونَهُ إِلَى النَّارِ
