Ibrahim Taimi (may Allah have mercy on him) says that I found sixty companions of Abdullah (may Allah be pleased with him) in this mosque, the youngest of whom was "Harith bin Suwaid," and I heard them reciting {إذَا زُلْزِلَتْ… الخ }. When they reached (فَمَنْ یَعْمَلْ مِثْقَالَ ذَرَّۃٍ خَیْرًا یَرَہُ), they began to weep, then said that this is indeed a very severe reckoning.
