Overall meaning : The Inevitable Resurrection! What is the Inevitable Resurrection on which all facts will be brought to light? What will make you realise what the Inevitable Resurrection is and what its circumstances and terrors are?!
Thamud, Salih’s people, and ‘Aad, Hud’s people, denied the Day of Resurrection which will strike hearts with terror!
Thamud were destroyed by an abnormally deafening blast, and ‘Aad were destroyed by an extremely howling, violent gale, which Allah let loose on them for seven whole nights and eight whole days without a break, destroying them all! In the end, you could see the ‘Aad people lying dead as though they were fallen, uprooted trunks of hollow palm trees. Can you see any trace of them now after Allah has utterly wiped them out?!
