What is the difference between al-qadar, an-naṣīb, and al-maktūb, are they synonyms for one meaning, and does man have a hand in any of them?

Among the general public, the words "qadar" (divine decree), "naseeb" (predetermined share), and "maktub" (written, fated) collectively signify a matter predetermined from eternity, in which humans have no input. This is referred to as a cosmic, preordained matter, and it includes what Allah loves (like faith) and what He dislikes (like disobedience). The Islamic texts use the terms "qadar" and "maktub" to mean a predetermined matter, whereas the word "naseeb" has not been used in this sense.
