عَنْ أَبِي هُرَيْرَةَ رَضِيَ اللَّهُ عَنْهُ أَنَّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ قَالَ فِي هَذِهِ الْآيَةِ وَشَاهِدٍ وَمَشْهُودٍ [سورة البروج: ٣] قَالَ يَعْنِي لِلشَّاهِدِ يَوْمَ عَرَفَةَ وَالْمَشْهُودِ يَوْمَ الْقِيَامَةِ
It is narrated from Sayyiduna Abu Hurairah, may Allah be pleased with him, that the Noble Prophet, peace and blessings be upon him and his family, regarding this verse {وَشَاھِدٍ وَّ مَشْہُوْدٍ}, said: "The witness refers to the Day of Arafah and the promised refers to the Day of Resurrection."
