Tafsir of Ash-Shu`ara' 26:204

Would they then wish for Our torment to be hastened on! This is a denunciation and a threat, because they used to say to the Messenger, by way of denial, thinking it unlikely ever to happen:

ايتنا بعذاب الله

Bring Allah's torment upon us. (29:29) This is as Allah said:

ويستعجلونك بالعذاب

And they ask you to hasten on the torment... (29:53-55) Then Allah says:

أفرأيت إن متعناهم سنين
