The Earth is spherical despite what is popularly believed … the proof is that the Sun is always vertical to a particular spot on Earth. - Ibn Hazm

Whosoever has a natural leaning towards a science, even if it was less noble than another, should not abandon it for the other because if he did he would be like someone who would be growing coconuts in al-Andalus and olive trees in India, crops that would never fructify.

Whosoever rises above things of this world, in front of which you kneel is much stronger than you.

You came to me just before
the Christians rang their bells.
The half-moon was rising
looking like an old man's eyebrow
or a delicate instep.
And although it was still night
when you came a rainbow
gleamed on the horizon,
showing as many colours
as a peacock's tail.
