Concerning Allah's statement,

﴿وَإِذَا النُّفُوسُ زُوِّجَتْ ﴾

(And when the souls are joined with their mates.) meaning, every type (of soul) will be gathered with its peer (or mate). This is as Allah says,

﴿احْشُرُواْ الَّذِينَ ظَلَمُواْ وَأَزْوَجَهُمْ﴾

(It will be said to the angels): "Assemble those who did wrong, together with their companions (from the devils).) (37:22) Ibn Abi Hatim recorded from An-Nu`man bin Bashir that the Messenger of Allah said,

﴿وَإِذَا النُّفُوسُ زُوِّجَتْ ﴾

الضُّرَبَاءُ: كُلُّ رَجُلٍ مَعَ كُلِّ قَوْمٍ كَانُوا يَعْمَلُونَ عَمَلَهُ وَذَلِكَ بِأَنَّ اللهَ عَزَّ وَجَلَّ يَقُولُ:

﴿وَكُنتُمْ أَزْوَاجاً ثَلَـثَةً - فَأَصْحَـبُ الْمَيْمَنَةِ مَآ أَصْحَـبُ الْمَيْمَنَةِ - وَأَصْحَـبُ الْمَشْـَمَةِ مَآ أَصْحَـبُ الْمَشْـَمَةِ - وَالسَّـبِقُونَ السَّـبِقُونَ ﴾

هُمُ الضُّرَبَاء»

((And When the souls are joined with their mates.)( Those who are alike. Every man will be with every group of people who performed the same deeds that he did. (This is because Allah says, (And you (all) will be in three groups. So those on the Right Hand - how (fortunate) will be those on Right Hand! And those on the Left Hand - how (unfortunate) will be those on the Left Hand!) (56: 7-10) (They are those who are alike.)
