Per the midrash quoted in this answer, Hashem keeps all commandments, if so how does the midrash explain why Hashem makes it rain on Shabbat wouldn't that be a Zoreia - Sowing
See Rambam Hilchot Shabbat 8:2
אֲבָל הַמַּשְׁקֶה צְמָחִין וְאִילָנוֹת בְּשַׁבָּת הֲרֵי זֶה תּוֹלֶדֶת זוֹרֵעַ וְחַיָּב בְּכָל שֶׁהוּא.
In contrast, watering plants and trees on the Sabbath is considered merely a derivative of sowing
