M6:1406 — یار بد نیکوست بهر صبر را / که گشاید صبر کردن صدر را

Translation: A bad companion is good for the sake of patience; For practicing patience expands the breast. Meaning: Engaging with difficult companions or situations serves as an excellent practice for patience, which in turn expands one's inner capacity and spiritual breadth.

The couplet, "A bad companion is good for the sake of patience; for practicing patience expands the breast," presents a profound psychological and mystical insight. Here, Rumi extends the logic he previously applied to the "enemy," arguing that even an antagonist is, in a sense, necessary for the spiritual struggle (jihād) against the ego. He used the example of the peacock whose beautiful feathers, though a source of danger, become an opportunity to combat attachment. This struggle, Rumi implies, strengthens us and earns us spiritual merit.

Now, Rumi applies this same logic to the "bad companion" (yār-e bad). A difficult, disagreeable, or even ill-natured friend, contrary to initial perception, can be "good." But good for what? Not for conventional pleasure or utility, but "for the sake of patience." Such a companion provides a fertile ground for the practice of forbearance and endurance. This idea was not new to Rumi; Ghazali, in his Ihya al-Ulum, explicitly recommends befriending ill-tempered individuals to learn patience by enduring their injustices and thereby increasing one's own mildness and resilience. Of course, this path is not for everyone; for many, simply enduring the daily unkindness of others encountered in daily life is sufficient, serving, as mystics say, like a scrubbing cloth for the soul, cleansing its impurities.

What is the outcome of such patience? "For practicing patience expands the breast." Patience, Rumi asserts, opens the breast (ṣadr) and grants inner spaciousness. Ṣadr here symbolizes an open heart, broad perspective, and increased capacity for acceptance. When one exercises patience in the face of adversities or the undesirable traits of others, one's spiritual capacity grows. This opening of the breast is akin to wisdom and virtue; it is what is praised in the Quran regarding the prophets: "My Lord, expand for me my breast." An open breast prepares the vessel of being for receiving greater truths.

Rumi then offers natural and human examples of patience: the moon's patience with the darkness of night, which allows it to illuminate; the flower's patience with the thorn from which its fragrant aroma (azfar – intensely perfumed) arises; and even the patience of milk formed amidst blood and dung within the stomachs of animals – a point the Holy Quran also alludes to, which some commentators consider a scientific miracle.

Finally, the most significant example: the patience of the prophets with their deniers. The Quran explicitly states, "And thus We have made for every prophet an enemy from among the criminals." These enemies, though outwardly bothersome, inwardly provided the ground for the prophets' patience and forbearance to blossom, transforming them into "the special ones of God and masters of their age." This implies that in Rumi's worldview, even apparent misfortunes and evils have an inner, constructive function, and given patience, they become a ladder for the human soul's ascent. The fruit of this patience, though seemingly bitter, will undoubtedly be sweet.

Key takeaways

• Even a 'bad companion' is an opportunity for spiritual growth and virtue, not merely a source of annoyance.
• Practicing patience in the face of adversity, rather than avoiding it, expands one's spiritual capacity and 'opens the breast'.
• Enduring the injustices of others is a path to self-purification and cleansing the 'impurities of the soul'.
• Natural examples (moon and night, flower and thorn) demonstrate that patience is a constructive element throughout existence.
• The prophets' patience with their deniers transformed them into 'God's elect'; adversities can serve as a ladder for spiritual ascent.
