Sura 9 Aya 80

Translator	Translation
Ali Quli Qara'i	Whether you plead forgiveness for them or do not plead forgiveness for them, even if you plead forgiveness for them seventy times, Allah shall never forgive them because they defied Allah and His Apostle; and Allah does not guide the transgressing lot.
Pickthal	Ask forgiveness for them (O Muhammad), or ask not forgiveness for them; though thou ask forgiveness for them seventy times Allah will not forgive them. That is because they disbelieved in Allah and His messenger, and Allah guideth not wrongdoing folk.
Shakir	Ask forgiveness for them or do not ask forgiveness for them; even if you ask forgiveness for them seventy times, Allah will not forgive them; this is because they disbelieve in Allah and His Messenger, and Allah does not guide the transgressing people.
Yusufali	Whether thou ask for their forgiveness, or not, (their sin is unforgivable): if thou ask seventy times for their forgiveness, Allah will not forgive them: because they have rejected Allah and His Messenger: and Allah guideth not those who are perversely rebellious.
