1. I'm an Arabic to English poetry translation service. Here is the translation of the poem you provided:
I fell ill, unaware of my fever

2. Until my visitors told of your plight
So I said no fever would have struck me

3. Had you not fallen ill first
An illness, it is said, is a sign

4. That God has cured when He cured you
So if my soul and your soul agree

5. On this and that, on that and this
Then O my soul, be our mercy, not

6. Contrary to what the Lord named you
For you know, or will come to know
