M3:347 — او بر آرد از کدورت‌ها صفا / مر جفاهای تو را گیرد وفا

This beyt appears in a section where Rumi is urging the listener to cling to God, personified as the 'daring friend' (یار دلیر) who is beyond the limitations of this world. Rumi contrasts this divine friend with worldly companions who inevitably leave or disappoint. The couplet emphasizes God's transformative power: 'turbidities' (کدورت‌ها) refer to the spiritual impurities, anxieties, and moral failings that cloud the human heart. God is depicted as the one who can extract 'purity' (صفا) from these very conditions.

The second line, 'Your cruelties, He turns into faithfulness' (مر جفاهای تو را گیرد وفا), is particularly profound. 'Cruelties' (جفاها) here can refer to the harshness, neglect, or even unfaithfulness that humans exhibit, either towards God or towards themselves and others. Rumi suggests that God not only forgives these but actively transmutes them into 'faithfulness' (وفا) – a deep and abiding loyalty or devotion. This isn't a mere wiping away of sin, but an alchemical transformation of negative states into positive spiritual attributes, highlighting God's boundless mercy and ability to refine the human soul.
