In reality, the word kitman comes from the verb katama, which means to hide, to conceal.
As it appears from the different English equivalents of the word, it touches on so many aspects - some of which are good and others are bad.
Starting with the good aspects, we can say that a good type of kitman (concealment or hiding) is when you hide things still in process till they are complete. In our life, we may meet people who look with a malevolent eye to what we have, who are jealous that we have this and that, who are envious that we are blessed with this and that. Driven by their envy, hatred and dark intentions, they may plot for us or weave some traps. In order to be saved from their traps, we should keep hush-hush on things that are still in preparation. To this type of hiding, kitman is the best policy. In this regard, the Prophet, peace and blessings be upon him, says in the hadith: “Seek fulfillment for things you want to finish inkitman.”
He himself gave the best example of such a type in the early days of Islam. When the number of Muslims was still small and the community was still weak, there was a big need for concealment or secret call (kitman) so as to save the cause of da`wah (inviting people to Islam) from the fierce enemies.
