ٱسۡتَغۡفِرۡ لَهُمۡ أَوۡ لَا تَسۡتَغۡفِرۡ لَهُمۡ إِن تَسۡتَغۡفِرۡ لَهُمۡ سَبۡعِينَ مَرَّةً فَلَن يَغۡفِرَ ٱللَّهُ لَهُمۡ ۚ ذَٰلِكَ بِأَنَّهُمۡ كَفَرُواْ بِٱللَّهِ وَرَسُولِهِۦ ۗ وَٱللَّهُ لَا يَهۡدِى ٱلۡقَوۡمَ ٱلۡفَٰسِقِينَ
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.<br/>
Ask forgiveness for them, O Muhammad may peace and salutation be upon him, or do not ask forgiveness for them: this leaves the choice of asking forgiveness, or refraining, up to him; the Prophet may peace and salutation be upon him said, 'I have been given the choice, and I made it', meaning [the choice] to ask forgiveness, as reported by al-Bukhaaree. If you ask forgiveness for them seventy times, God will not forgive them: it is said that the 'seventy' is intended to express [by hyperbole] a great frequency of asking forgiveness. In [the Saheeh of] al-Bukhaaree there is a hadeeth [which states]: 'If I was sure that were I to ask more than seventy times, God would forgive [them], I would have done so'. It is also said, however, that the very number [seventy] is actually meant, on account of this other hadeeth of his: 'I shall ask more than seventy times', whereupon it was made clear to him [the Prophet] that the matter regarding forgiveness had been concluded by the verse, [Q. 63:6] Alike it will be regarding them: whether you ask forgiveness for them or you do not ask forgiveness for them [God will not forgive them]; that is because they disbelieved in God and His Messenger; and God does not guide the wicked folk.
