When the winds blow severely,

 When the winds blow severely, rains fall fiercely, the lightning flashes, the thunder roars, the bold descends and storms of trial become severe, grieve not; for after this storm, verily, the divine spring will arrive, the hills and fields will become verdant, the expanses of grain will joyfully wave, the earth will become covered with blossoms, the trees will be clothed with green garments and adorned with  blossoms and fruits. Thus blessings become manifest in all countries. These favors are results of those storms and hurricanes.
The discerning man rejoiceth at the day of trials, his breast becometh dilated at the time of severe storms, his eyes become brightened when seeing the showers of rain and gusts of wind, whereby trees are uprooted; because he foreseeth the result and the end (of these trials), the leaves, blossoms and fruits (which follow this wintry storm); while the ignorant (short-sighted) person becometh troubled when he seeth a storm, is saddened when it raineth severely, is terrified by the thunder and trembleth at the surging of the waves which storm the shores.
