*41) Different words have been used for this torment at different places in the Qur'an. Somewhere it has been called rajfah (a frightful and shocking calamity), somewhere saihah (a crashing and thundering disaster), somewhere taghiyah (a most severe affliction) and here it has been described as sa'iqah (a calamity that strikes like a thunderbolt). Probably this torment had occurred as an earthquake which was also accompanied by a terrible noise.
