Ibn ʿAbbas said to me and to his son ʿAli, "Go to Abu Saʿid and listen to what he narrates." So we went and found him in a garden looking after it. He picked up his Rida', wore it and sat down and started narrating till the topic of the construction of the mosque reached. He said, "We were carrying one adobe at a time while ʿAmmar was carrying two. The Prophet ﷺ saw him and started removing the dust from his body and said, "May Allah be Merciful to ʿAmmar. He will be inviting them (i.e. his murderers, the rebellious group) to Paradise and they will invite him to Hell-fire." ʿAmmar said, "I seek refuge with Allah from affliction."  

كُنَّا نَحْمِلُ لَبِنَةً لَبِنَةً وَعَمَّارٌ لَبِنَتَيْنِ لَبِنَتَيْنِ فَرَآهُ النَّبِيُّ ﷺ فَيَنْفُضُ التُّرَابَ عَنْهُ وَيَقُولُ وَيْحَ عَمَّارٍ تَقْتُلُهُ الْفِئَةُ الْبَاغِيَةُ يَدْعُوهُمْ إِلَى الْجَنَّةِ وَيَدْعُونَهُ إِلَى النَّارِ قَالَ يَقُولُ عَمَّارٌ أَعُوذُ بِاللَّهِ مِنَ الْفِتَنِ
