hi esma
do u wanna a translation for this sentence??
اذا: means "If"
المرؤ: means "one", "someone", "person"
لا: it used her for negation
يرعاك: means " take care of u"
الا: means "only", "but"
تكلفا: means "Smirking", "overacted person when he treats with others"
the whole sentence means: that someone doesnt take care of u, but if he takes care of u he will be overacted with u
