Sura 11 Aya 8

Translator	Translation
Ali Quli Qara'i	And if We defer their punishment until a certain time, they will surely say, ‘What holds it back?’ Look! On the day it overtakes them it shall not be turned away from them, and they will be besieged by what they used to deride.
Pickthal	And if We delay for them the doom until a reckoned time, they will surely say: What withholdeth it? Verily on the day when it cometh unto them, it cannot be averted from them, and that which they derided will surround them.
Shakir	And if We hold back from them the punishment until a stated period of time, they will certainly say: What prevents it? Now surely on the day when it will come to them, it shall not be averted from them and that which they scoffed at shall beset them.
Yusufali	If We delay the penalty for them for a definite term, they are sure to say, "What keeps it back?" Ah! On the day it (actually) reaches them, nothing will turn it away from them, and they will be completely encircled by that which they used to mock at!
