وَغَدَاةَ رِيحٍ قَدْ وَزَعْتُ وَقَرَّةٍ قَدْ أَصْبَحَتْ يَدُ الشَّمَالِ زِمَامَهَا
On many a morning of biting wind and cold, when the north wind seemed to hold the day by its reins, I countered its harshness by helping others.
Wazaʿtu expresses restraining or checking. The commentary understands his response to the bitter weather as feeding and assisting people, not literally controlling the wind. Yadu al-shamāli zimāmahā personifies the north wind as a hand holding reins.
