السلام عليكم ورحمة الله وبركاته احسن الله إليكم Is it allowed to say "Allahummah Barik" to Kuffar if you see something that is good or you like, e.g. a car or house جزاك اللهُ خيرا

Ustadh AbdulAziz al-Haqqan

If what is meant is that u dont harm him through the evil eye, then it seems to me that it is allowed as we can do ruqyah upon disbelievers, and Allah knows best.
