Dalail il khayrat is a compilation of praises upon the messenger Muhammad peace be upon him... This is my favourite excerpt:
The messenger of Allah peace and blessings of Allah be upon him said:
There is not one slave that sends praises on me except that it exits from his lips hurriedly
so that no place is left from the shores, or the oceans or the east or the west
except that that praise goes past it and says
"I am the salawaat of so and so son of so and so, he praised Muhammed the chosen one, best of all of Allah's creation"
thereafter no thing remains unless it praises that person .
And created forth from that single praise is a bird which has 70,000 wings
and on each wing 70,000 feathers
and on each feather 70,000 faces,
and on each face 70,000 lips
and from each lip 70,000 tongues
that praise Allah Most-High with 70,000 languages
and Allah has recorded for him
the reward of all those praises.
Allahuma sally 'ala sayyidina Muhammad wa 'ala aalihi wasahbihi wasalim
