﴿ وَمَا كَانَ ٱللَّهُ لِيُعَذِّبَهُمْ وَأَنتَ فِيهِمْ ۚ وَمَا كَانَ ٱللَّهُ مُعَذِّبَهُمْ وَهُمْ يَسْتَغْفِرُونَ ﴾

“But God did not choose thus to chastise them whip thou [O Prophet] wert still among them, nor would God chastise them when they [might yet] ask for forgiveness.”

(But Allah would not punish them) Allah would not destroy Abu Jahl and his host (while thou wast) residing (with them, nor will He punish them) destroy them (while they seek forgiveness) while they desire to believe.
