Is it permissible to respond to Denmark with offensive caricatures that do not touch upon religion?

It is not wise to retaliate against someone who insults the religion, the Book, or the Prophet by insulting them back, due to the Almighty's saying: "And do not insult those they invoke other than Allah, lest they insult Allah in enmity without knowledge." The conditions for supplication are: sincerity to Allah, not supplicating for a sin or breaking ties of kinship, not asking for the impossible, and presence of heart. Supplication after the obligatory prayer is more likely to be answered, as stated in the Hadith narrated by Tirmidhi.
