Hi Kate, Icouldnt listen to this song anywhere on youtube so I cant verify If the arabic text youve posted is 100% correct .There is a sentence or two which are slightly odd.However having said that ,Ehab is famous for focusing on the tune/ melody and neglecting the words/lyrics- they are usually not very compatible or in harmony with one another!.
Happy Dancing :)

أه يا حبيبى يا شاغل بالى عمرى ليك يا غالى
O my lover [whose]occupying my mind! ,my age [life] is yours O preciouse [one]
قلبى داب ليالى وأنت ليه نسينى تعالى شوف حنينى
My heart has continued for nights ,and why are you forgetting me!,come see my longing!

أه يا حبيبى يا شاغل بالى أنت اللى فى أيديك
O my lover O[one]who is on my mind ,you are the one in your hands
عمرى وأحلامى وملكت بقلبك روحى وأيامى
[you are] my age [life] and dreams,and youve possessed with your heart my soul and my days
ده أنا قلبى مولع نار وسيبنى أسهر وأحتار
my heart is on fire ! leave me stay up late and confused
أرجعلى حرام ده فى قلبى غرام مشتاق لعنيك
come back to me! its a sin!, there is passion in my heart,I long for your eyes

أه ياحبيبى يا شاغل بالى حبيبى
O my lover [whose] occupying my mind!, my lover
لا كفاية تعالى عيش معايا
No!,enough,come live with me
وأنت ليه نسينى تعالى شوف حنينى
And why are you forgetting me!,come see my longing.
