In Nahj al-Balagha, Imam Ali (AS) has expressed statements that evoke the idea of "fortune, luck, and chance". In one of his sayings, he advises partnering with fortunate individuals: "Sustenance has turned toward him". Elsewhere, he states: "If fortune smiles upon you, your faults remain concealed". Some commentators interpret these phrases as indicating that fortune and luck are events that, without any apparent reason, bestow their favors upon certain individuals. Associating with such fortunate people, they argue, leads to the transmission of their luck, ultimately benefiting one immensely. On the other hand, another group contends that nothing in existence happens without cause, and it is impossible to ignore the underlying factors contributing to one's success and well-being. This research, employing a descriptive-analytical method, examines Imam Ali's (AS) statements in light of the commentaries on Nahj al-Balagha. The findings indicate that in pre-Islamic beliefs, fortune and luck indiscriminately cast their shadow upon certain individuals, granting them prosperity from all directions. However, in the Qur’an and the sayings of Imam Ali (AS), while a cause may produce an unexpected effect—leading the human mind to misidentify the primary reason behind an occurrence—no event is entirely random or accidental. The emphasis placed on diligence and effort, along with recommendations for specific guidelines to enhance sustenance and attain happiness and prosperity in the words of the Commander of the Faithful, serve as evidence of this principle.
