وَٱصْبِرْ عَلَىٰ مَا يَقُولُونَ وَٱهْجُرْهُمْ هَجْرًا جَمِيلًا
Wasbir 'alaa maa yaqoo loona wahjurhum hajran jameelaa
Bear patiently what they say, and part from them with a gracious parting.
Jamīl qualifies hard actions done well: patience under loss, overlooking an offence, releasing a wife, and here a withdrawal. This is the only place it attaches to hajr, the word for leaving people behind, and the pairing sets a limit — the parting is to carry no retaliation in it. What follows hands the deniers over to God, so the matter continues in other hands.
