Holy Quran » AL 'ANKABUUT : 53

And they urge you to hasten the punishment. And if not for [the decree of] a specified term, punishment would have reached them. But it will surely come to them suddenly while they perceive not.

{ويستعجلونك بالعذاب ولولا أجل مسمى} له {لجاءَهم العذاب} عاجلاً {ولياتينَّهم بغتةً وهم لا يشعرون} بوقت إتيانه.
