A soul denotes the combination of the live substance and the spirit. Allah (swt) says:

   ﴾اللَّهُ يَتَوَفَّى الْأَنفُسَ حِينَ مَوْتِهَا ﴿

(Allah takes the souls at the time of their death,) (Az-Zumar: 42)

Taking the soul means separating the spirit from the body. After that, on the Resurrection Day, the spirits will be returned to their bodies again.

زُوِّجَتْ (are paired): Each same kind will be gathered.
