TITLE UNKNOWN ??? - Abu Hamid Al Ghazali

Tell thou to my friends when weeping
They my words decry
Here you find my body sleeping
But it is not I

Now in life immortal hovering
Far away I roam
This was my house my covering
Tis no more my home

This was as the cage that bound me:
I, the bird have flown
This was but the shell around me
I, the pearl, am gone

Over me as o'er a treasure
Had a spell been cast
God hath spoken at his pleasure
I am free at last

          Abu Hamid Al Ghazali
