M3:505 — من رباح الله کونوا رابحین / ان ربی لا یحب الفرحین

This couplet marks a crucial turning point in the narrative. The Khwaja and his family are joyfully heading to the village, anticipating material gains and comfort. They are 'excessively joyful' (فرحین) over the prospect of worldly profit. However, an inner voice, personified as 'Reason' (عقل) or divine guidance, interjects with a warning. The first hemistich, 'I am the profit of God; be you also profitable!' (من رباح الله کونوا رابحین), is presented as a divine utterance, reminding the travelers that real 'profit' (رباح) is spiritual, found in God, not in the fleeting pleasures of the world. The second hemistich, 'Indeed, my Lord loves not the excessively joyful' (ان ربی لا یحب الفرحین), is a direct quote from the Quran (28:76), specifically referring to Qarun, a wealthy man who was arrogant and excessively joyful about his riches, leading to his downfall. Rumi uses this Quranic verse to underscore the Sufi principle that attachment to worldly joy and material gain is a veil between the seeker and God. True joy, as the subsequent verses elaborate, should stem only from the Divine, and even sorrow can be a path to spiritual ascent.
