In every country there is a harbour (a landing place where one may make good transactions. Allah’s grace is not restricted to a particular place). But one cannot expect it on a sandy waste land completely void of the basic favourable condition (faith). An ascetic, a wearer of beggar’s raiment, who renounces the world, will be able to collect gems in abundance (i.e. receive Allah’s grace in plenty).
TRADITION: The faith of a person is slender if his clothes are thin (i.e. of finer stuff).

There is not much wroth in harbours with sand and ports all o'er,
pearls and precious stones you will only find in sufi's lore.

Ports are there country to country but pearls cannot be had for sand,
Yet those who in beggars' rags are bestowed pearls without weighing.
