Abu Sa'id told that God's messenger mentioned the one who Would blow the trumpet, saying that Gabriel would be at his right hand and Michael at his left.
وَعَنْ أَبِي سَعِيدٍ قَالَ: ذَكَرَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ صَاحِبُ الصُّورِ وَقَالَ: «عَن يَمِينه جِبْرِيل عَن يسَاره مِيكَائِيل»
