salah involves surat al fatihah followed by either quls or in many cases baqarah
here is what baqarah says about non-muslims
"For disbelievers is a painful doom." 2:104 Allah will make disbelievers' lives miserable in this world and torture them forever after they die. 2:114 They will not emerge from the Fire. 2:167 Disbelievers worship false gods. The will burn forever in the Fire. 2:257 Apostates will be cursed by Allah, angels, and men. They will have a painful doom. 3:86-88
and this is barely touching the rest,
and that's the job of imams here is an official source that not only says to recite in prayers but also after waking up
idk what mazhab you follow are you a shia?
