وَإِنَّ الْعَشَرَةَ الَّذِينَ سَمَّاهُمْ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَبَشَّرَهُمْ بِالْجَنَّةِ نَشْهَدُ لَهُمْ بِالْجَنَّةِ عَلَى مَا شَهِدَ لَهُمْ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَقَوْلُهُ الْحَقُّ
We testify to Paradise for the ten named by the Messenger of Allah ﷺ and given glad tidings of Paradise, because his testimony is true.
Al-ʿAsharah al-Mubashsharah are the ten Companions specifically named as recipients of this prophetic promise. Affirmation of Paradise for them rests on the report of the Prophet ﷺ.
