﴿ سَيَهْدِيهِمْ وَيُصْلِحُ بَالَهُمْ ﴾

“He will guide them [in the hereafter as well], and will set their hearts at rest,”

He will guide them in this world and in the Hereafter to what benefits them and rightly dispose their minds their condition in both with that guidance and disposal in this world being for those who were not slain but who have been included in the statement ‘and those who were slain’ qutilū because of the predominance therein of those who were slain.
