Explanation

The wind is from Allah's mercy for His slaves. It brings mercy, and it brings punishment. Allah sends the wind as a mercy for His slaves, and it results in much goodness and blessings for the people. Allah says in the Qur'an: {And We have sent the fertilizing winds} [Sūrat al-Hijr: 22]. {It is Allah who sends the winds, and they stir the clouds and spread them in the sky however He wills, and He makes them fragments so you see the rain emerge from within them} [Sūrat Ar-Rūm: 48]. {And it is He who sends the winds as good tidings before His mercy until, when they have carried heavy rainclouds, We drive them to a dead land and We send down rain therein, and bring forth thereby [some] of all the fruits} [Sūrat al-A‘rāf: 57]. It also brings punishment as explained by the following verses in the Qur'an: {So We sent upon them a screaming wind during days of misfortune to make them taste the punishment of disgrace in the worldly life} [Sūrat Fussilat: 16]. {Indeed, We sent upon them a screaming wind on a day of continuous misfortune. Extracting the people as if they were trunks of palm trees uprooted} [Sūrat al-Qamar: 19-20]. {And when they saw it as a cloud approaching their valleys, they said: "This is a cloud bringing us rain!" Rather, it is that for which you were impatient: a wind, within it a painful punishment} [Sūrat al-Ahqāf: 24]. The Prophet (may Allah's peace and blessings be upon him) said: "When you see it, do not swear at it," i.e. it is not permitted for a Muslim to curse the wind, because it is a creation of Allah and it is ordered by Him to do what it does, and it has no real effect in itself. It neither harms nor benefits except with the orders it takes from Allah. Therefore, swearing at the wind is equivalent to swearing at the One who creates and controls it, namely, Allah, the Almighty. "Ask Allah for its goodness and seek Allah's refuge from its evil", i.e. after the Prophet (may Allah's peace and blessings be upon him) forbade swearing at the wind, he directed his nation to ask Allah for its good and seek refuge from its evil when it blows. In other words, they should ask Allah that the good that it carries be delivered to them, and that the evil that it carries be diverted away from them.
