It was also said that “those” retains its usual sense, because it refers to slaves together with livestock.
It was also said that “those” is governed by the preposition, being coordinated with the pronoun in “for you.”
“There is not a thing but that its treasuries are with Us, and We send it down only in a known measure (21). And We send the fertilizing winds, then send down water from the sky and give it to you to drink; yet you are not its keepers (22).”
“There is not a thing”—that is, there is nothing—“but that its treasuries are with Us”: that is, the keys to its treasuries. It was also said that this refers to rain.
“And We send it down only in a known measure”: every land has an apportioned limit. It is said that not a single drop descends from the sky except that an angel accompanies it, directing it wherever Allah, exalted is He, wills and wishes.
It is related from Ja‘far ibn Muhammad, from his father, from his grandfather, that he said: “Upon the Throne is a likeness of everything Allah has created on land and at sea. This is the interpretation of His saying, Most High: ‘There is not a thing but that its treasuries are with Us.’” (2)
“And We send the fertilizing winds”: that is, winds bearing water, because they carry water to the clouds. The word is the plural of “bearing,” as one says of a she-camel when she is carrying a young.
Ibn Mas‘ud said: “Allah sends the wind, and it carries the water. The clouds then pass over it, and they pour forth as a pregnant she-camel pours forth milk; then they rain.” (3)
Abu ‘Ubaydah said: By “the fertilizing winds,” He meant “the pollinating winds,” whose singular form is “a pollinating wind,” because they pollinate the trees.
‘Ubayd ibn ‘Umayr said: “Allah sends the heralding wind, and it thoroughly sweeps the earth. Then Allah sends the stirring wind, which stirs up the clouds. Then Allah sends the joining wind, which brings the clouds together and makes them into piled masses. Then He sends the fertilizing winds, which pollinate the trees.” (4)
Abu Bakr ibn ‘Ayyash said: “Not a drop falls from a cloud until the four winds have acted upon it: the east wind stirs it up, the north wind gathers it, the south wind scatters it, and the west wind disperses it.”
It is reported that the fertilizing winds are the south winds.
