و القلب أهو داب Please note this is not the Standard Arabic, what I wrote is a dialect.

هذه اللهجة المصرية و ليست اللغة العربية الفصحى بالعربية نقول : ذاب القلب

ذاب القلب = The heart has melted يذوب القلب = yadoobu lqalbu = The heart melts

و القلب أهو داب

" Wal galb aho dab " والجلب اهو داب " What I translated to called "See'de dialect" It's exist in Egypt :) because you wrote " wal Galb NOT wal Qalb " " wal qalb aho dab والقلب أهو داب " in case of you meant this. Hope you got it :) Good luck.
