The following is taken from Night 13, The Arabian Nights, the new translation by Malcolm Lyons. I think I have blogged quite a bit about the wonder of this translation. All writers should remember this:
'The writer perishes but what he writes
Remains recorded for all time.
Write only what you will be pleased to see
When the Day of Resurrection comes
Open the inkwell of grandeur and of blessings;
Make generosity and liberality your ink.
When you are able, write down what is good;
This will be taken as your lineage and that of your pen.
