Praying for the kaafir to be guided or else be punished by Allaah

This is not letting Allaah choose, rather it is asking for
them to be guided by Allaah, whilst referring the matter of their being
guided to His will and wisdom. If that is done for them then praise be to
Allaah, otherwise may Allaah protect us against their evil by seizing them
with such a penalty that comes from One exalted in power and able to carry
out His will, as a punishment for their wrongdoing and so as to cleanse the
earth of their filth. So it is a permissible du’aa’. 

And Allaah is the Source of strength, May Allaah send
blessings and peace upon our Prophet Muhammad and his family and
companions.
