The Messenger of Allah ﷺ said, "Allah will send a wind from Yemen, softer than silk, that will not leave anyone with even a grain's weight, or an atom's weight, of faith in his heart without taking his soul."
قال رسول الله ﷺ: إن الله يبعث ريحا من اليمن ألين من الحرير، فلا تدع أحدا في قلبه مثقال حبة- أو مثقال ذرة- من إيمان إلا قبضته.
Muslim narrated it in the Book of Iman (117:185) through Safwan bin Salim, from Abdullah bin Salman, from his father, from Abu Hurairah, and he related it.His saying, "softer than silk," means a gentle breeze with no dust in it and no turbulence, like the morning breeze.His saying, "Allah will send a wind from Yemen," and it has come in the previous hadith of Abdullah bin Amr bin As, "then Allah will send a cold wind from the direction of Sham." There are several ways to reconcile the two, and the one most fitting to me is that they are two winds.1- The wind of Yemen, which encompasses the Arabian Peninsula and the surrounding countries such as Persia, Turkestan, India, Afghanistan, and others.2- The wind of Sham, which encompasses the lands of Sham, Europe, and whatever inhabited lands were discovered afterward, such as America, Australia, and other islands, because Sham was under the Roman Empire.It has also been said that it begins in one of the two regions and reaches the other. If this interpretation is correct, then it must begin from Yemen, which encompasses the Arabian Peninsula and its surroundings, and end in the lands of Sham, meaning Europe and whatever inhabited lands were discovered, such as America, Australia, and others.As for what has been narrated from Burayda bin Husayb, who said, "I heard the Prophet ﷺ say, 'At the turn of a hundred years, Allah will send a cold wind that will take the soul of every Muslim,'" this contains an irregularity.Bukhari narrated it in Tarikh al-Kabir (2/101–102), Bazzar (4420), and Hakim (4/457), all through routes from Bashir bin Muhajir, from Abdullah bin Burayda, from his father, and he related it.Bazzar said, "We do not know this hadith to be narrated with this wording except from Burayda through this chain." Hakim said, "This is a hadith sahih in its chain." Ibn Hajar said in Matalib (4349), "Its chain is hasan."I say, in its chain is Bashir bin Muhajir, who is disputed, and to me his hadith is hasan when he does not come with something objectionable. This hadith is among those objected against him. Bukhari said in the biography of Bashir in Tarikh al-Kabir (2/102), "He contradicts others in some of his hadith, and this is one of them," and Dhahabi included it among his irregular narrations in Mizan. The text itself is problematic.If what is meant is a hundred years after the death of the Prophet ﷺ, then this contradicts reality, and if what is meant is before the establishment of the Hour, then specifying a hundred years has no meaning, since this is not mentioned in the sahih hadiths where it is stated that Allah will send a wind before the establishment of the Hour that will take the soul of every believer.Perhaps the hadith about the extinction of the generation of the companions after a hundred years became mixed into the hadith about the sending of the wind that takes the souls of the believers before the establishment of the Hour. And Allah knows best.
