la tgoul 3andi as7ab
la tgoul a7beb
don't say that you have friends or beloved ones
ya sa7bi ma kont ndhonek haka
I didn't think that you are like that Oh friend
ana dhanitek sess s7i7 3lih netakka
I thought you were a good base on which I can lie
jey el youm tetnedim tetbakka
you came today to cry and to regret
3lech fi ghyebi ma 9ritlich 7sseb
why during my absence you didn't count me

la la la tgoul 3andi la tgoul 3andi as7ab
don't say that you have beloved ones

essa7eb le7ssebtou khou ghdar we khan el 3echra
the friend you though a brother,betrayed and denied gregariousness
t9elbet layem we walla 3dou we badel 9echra
days went upside down and he became an enemy,he changed his skin

baddal as3ab law9at be dmou3 3al khdoud
he changed the most difficult moments with tears on the cheeks
baddal a7la dha7ket be a7zen ma leha 7doud
he changed the sweetest laughter with unlimited grieves

ma kenech 3al bel wala 3al khater ywedni lyoum bghdra
I didn't see it coming,I didn't think he'd betray me
elli ken 3ziz 3liya jra7ni jor7 ma yabra
the one that was dear to my heart,caused me an non healing wound

to7t ke dam3a men 3ini lyoum eb3ed khallini
you went down from my eyes like a tear,so leave alone today
ghadrek ma nenseh marsoum 3ala jbini
I can't forget your betrayal it is written on my forehead


dhawagtni essam tezd fi galbi ham
you make me eat the poison,worries got bigger in my heart
ekthor zmam we ghom lin wallit nebki dam
grieves have increased till I cried blood

wallah kthor el ham m5obi hammi bdhe7ka
I am so sad ,hiding my concerns with a smile
kol ensen iy3ich we ma yeb9a yetbakka
every human being lives without crying

ba3da eddnya hakka we ma3linech elloum
life is like this,we are not to be blamed
rajel 3omrou ma yaghder mais 3adi yti7 we y9oum
a man never betrays but it is normal that he falls and then stands up

ti chay maydoom ya dhalem we yjik nhar
nothing continues,a day will come Oh cruel
kif ma bke galbi dam lezmek tdhoug el mrar
you should taste the biterness like my heart cried blood

ghiri ki nadelek 3titou galbek we 3inik
when someone else called you,you gave him his heart and eyes
ma jech 3la belek jey bech ybadda3 bik
it never crossed your mind that he'd stab you in the back
we lyoum tkhalles elli nselek kahless eddin elli 3lik
and today you have to pay what you owe me
meni nsi7a dirha fi belek ekher kelma meni lik
take it as an advice from me ,my last word from me to you

Thank you !
