يَمِينًا لَنِعْمَ السَّيِّدَانِ وُجِدْتُمَا ۞ عَلَى كُلِّ حَالٍ مِنْ سَحِيلٍ وَمُبْرَمِ
Meaning: By an oath: you two have proved excellent leaders in every condition, whether loosely spun or firmly twisted.
Yamīnan reinforces the oath. La-niʿma al-sayyidāni is a formula of praise, while wujidtumā is a second-person dual passive: “you two were found/proved to be.” The leaders are praised on the evidence of their conduct.
Saḥīl evokes a loosely spun strand, and mubram a firmly twisted cord. Their contrast is not literally about rope-making: it illustrates steadfast leadership through different or difficult conditions.
