Here you would see scan page from known shia book “Mafatih al-jinan” by Abbas Qummi.

In the footnote you can read:

Allama Majlisi said: Ayatul Kursi as it was revealed in accordance to narration of Ali ibn Ibrahim al-Qummi is like this: Allah is He besides Whom there is no god, the Everliving, the Self-subsisting by Whom all subsist; slumber does not overtake Him nor sleep; whatever is in the heavens and whatever is in the earth, and between them and under the land  is His. He knows unseen and apparent. Ar-Rahman and Ar-Rahim …. till …. they would remind there forever”.

Just presenting real verse to compare:

[Shakir 2:255] Allah is He besides Whom there is no god, the Everliving, the Self-subsisting by Whom all subsist; slumber does not overtake Him nor sleep; whatever is in the heavens and whatever is in the earth is His; who is he that can intercede with Him but by His permission? He knows what is before them and what is behind them, and they cannot comprehend anything out of His knowledge except what He pleases, His knowledge extends over the heavens and the earth, and the preservation of them both tires Him not, and He is the Most High, the Great.
