Allah commands His Messenger, peace be upon him,

[فَإِن رَّجَعَكَ اللَّهُ]

(If Allah brings you back), from this battle,

[إِلَى طَآئِفَةٍ مِّنْهُمْ]

(to a party of them) in reference to the twelve (hypocrite) men, according to Qatadah,

[فَاسْتَأْذَنُوكَ لِلْخُرُوجِ]

(and they ask your permission to go out), with you to another battle,

[فَقُلْ لَّن تَخْرُجُواْ مَعِىَ أَبَدًا وَلَن تُقَـتِلُواْ مَعِىَ عَدُوًّا]

(say: "Never shall you go out with me nor fight an enemy with me...'') as an admonishment and punishment for them. Allah mentioned the reason for this decision,

[إِنَّكُمْ رَضِيتُمْ بِالْقُعُودِ أَوَّلَ مَرَّةٍ]

("You were pleased to sit (inactive) on the first occasion...'') Allah said in a similar Ayah,

[وَنُقَلِّبُ أَفْئِدَتَهُمْ وَأَبْصَـرَهُمْ كَمَا لَمْ يُؤْمِنُواْ بِهِ أَوَّلَ مَرَّةٍ]

(And We shall turn their hearts and their eyes away (from guidance), as they refused to believe therein for the first time. ) [6:110] The recompense of an evil deed includes being directed to follow it with another evil deed, while the reward of a good deed includes being directed to another good deed after it. For instance, Allah said concerning the `Umrah of Hudaybiyyah,

[سَيَقُولُ الْمُخَلَّفُونَ إِذَا انطَلَقْتُمْ إِلَى مَغَانِمَ لِتَأْخُذُوهَا]

(Those who lagged behind will say, when you set forth to take the spoils.)[48:15] Allah said next,

[فَاقْعُدُواْ مَعَ الْخَـلِفِينَ]

("...then you sit (now) with those who lag behind.'') in reference to the men who lagged behind from [Tabuk] battle, according to Ibn `Abbas.

[وَلاَ تُصَلِّ عَلَى أَحَدٍ مِّنْهُم مَّاتَ أَبَداً وَلاَ تَقُمْ عَلَى قَبْرِهِ إِنَّهُمْ كَفَرُواْ بِاللَّهِ وَرَسُولِهِ وَمَاتُواْ وَهُمْ فَـسِقُونَ ]

(84. And never (O Muhammad ) pray (funeral prayer) for any of them (hypocrites) who dies, nor stand at his grave. Certainly they disbelieved in Allah and His Messenger, and died while they were Fasiqun.)
