Yusuf Ali
They ask thee to hasten on the Punishment (for them): had it not been for a term (of respite) appointed, the Punishment would certainly have come to them: and it will certainly reach them,- of a sudden, while they perceive not!

Sahih International
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.

Shakir
And they ask you to hasten on the chastisement; and had not a term been appointed, the chastisement would certainly have come to them; and most certainly it will come to them all of a sudden while they will not perceive.

Pickthall
They bid thee hasten on the doom (of Allah). And if a term had not been appointed, the doom would assuredly have come unto them (ere now). And verily it will come upon them suddenly when they perceive not.

محمد جالندھری
اور یہ لوگ تم سے عذاب کے لئے جلدی کر رہے ہیں۔ اگر ایک وقت مقرر نہ( ہو چکا) ہوتا تو اُن پر عذاب آبھی گیا ہوتا۔ اور وہ (کسی وقت میں) اُن پر ضرور ناگہاں آکر رہے گا اور اُن کو معلوم بھی نہ ہوگا
