Almuntakhab Fi Tafsir Alquran Alkarim

Allah, my Creator, Shuaib said is Omnipresent and He is fully cognizant of all that you do

Tafseer Tafheem-ul-Quran by Syed Abu-al-A'la Maududi

(26:188) Shu'aib said, "My Lord knows whatever you are doing." *116

He said, "My Lord is most knowing of what you do." meaning

*116) That is, "It is not in my power to bring down the torment; it is in Allah's power, and He is fully aware of your misdeeds. He will send down the torment as and when He wills." In this demand of the people of Aiykah and the answer of Prophet Shu'aib to them there was an admonition for the Quraish as well. They also demanded from the Holy Prophet to bring down the torment on them: "Or.... you cause the sky to fall down on us in fragments, as you threaten us." (Bani Isra'il: 92). As such the Quraish are being told that the people of Aiykah had also demanded a similar thing from their Prophet, and the answer that they got from their Prophet is the answer of Muhammad (Allah's peace be on him) to you.
