I want to know, what is the suitable permissible work for a Muslim?

The majority of scholars hold that the default rule for things is permissibility, citing Allah's saying: "He it is Who created for you all that is in the earth," and the hadith: "What Allah has made lawful in His Book is lawful, and what He has made unlawful is unlawful, and what He has remained silent about, that is pardoned." The default rule for contracts is validity unless there is evidence of invalidity. It is impossible to enumerate all permissible professions for a Muslim, for the default rule is permissibility unless there is a legal prohibition. Trade, leasing, agriculture, industry, and other professions are permissible if they adhere to the Islamic legal guidelines. What suits a person depends on their circumstances and capabilities. And Allah knows best.
