Explanation

This Hadīth narrates a story about a slave who made a contract with his master to pay him for his emancipation in installments, but he had no money to pay his master. He went to ‘Ali ibn Abi Tālib (may Allah be pleased with him) so that he might help him pay off his debt. ‘Ali (may Allah be pleased with him) guided him to this divine remedy, which is a supplication that the Prophet (may Allah's peace and blessings be upon him) taught him to say. Whoever says it sincerely, Allah will pay off his debt on his behalf, even if it is as huge as a mountain. He told him to say: "O Allah, Grant me enough of what You make lawful so that I may cast aside what You make unlawful, and bestow upon me Your favor so that I may dispense with all but You.”
