1. The one whom I desire, I do not name outright
Yet hints aplenty about him I shall cite

2. If you seek his ratio in numbers to find
The square root of first is ten times the second in kind

3. And if to that root you add a fourth part seen
You will find as the third a meaning most keen

4. And half of it was beloved by the Abbasid's sister renowned
So his past and future are clearly spelled out on this ground
