Is marriage obligatory for a Muslim, and will he be punished if he does not marry, or is he not sinful if he abandons marriage and dedicates himself to worship, travel, and enjoying life without disobedience?

Abandoning marriage may be contrary to what is superior. If a Muslim does not fear temptation for himself and dedicates himself to worship, knowledge, and da'wah (calling to Islam), then he will be rewarded. It is advisable to establish a Muslim household and marry women from the same nationality to increase understanding. There is no objection to marrying a righteous European Muslim woman. Smoking is forbidden due to the diseases it causes.
