Surah Al-Baqarah is the second Surah in the Quran.
Surah Al-Baqarah Ayat 255 is also known as "Ayat Kursi". Its meaning is as follows:
"Allah, tidak ada Tuhan melainkan Dia yang hidup kekal lagi terus-menerus mengurus (makhlukNya), tidak mengantuk dan tidak tidur. KepunyaanNya apa yang ada di langit dan di bumi. Tiada yang dapat memberi syafaat di sisi Allah tanpa izinNya. Allah mengetahui apa yang di hadapan mereka dan di belakang mereka dan mereka tidak mengetahui apa-apa dari ilmu Allah melainkan apa yang dikehendakiNya. Kursi(4) Allah meliputi langit dan bumi. Dan Allah tidak merasa berat memelihara keduanya dan Allah Maha Tinggi, lagi Maha Besar.
(4) Sebahagian mufassir mengertikan Kursi dalam ayat ini dengan ilmu Allah dan ada pula yang mentafsirkan dengan kekuasaanNya.
From Quran databases at the Center for Muslim-Jewish Engagement, USA:
YUSUF ALI: Allah! There is no god but He,-the Living, the Self-subsisting,
Eternal. No slumber can seize Him nor sleep. His are all things in the
heavens and on earth. Who is there can intercede in His presence except as
He permitteth? He knoweth what (appeareth to His creatures as) before or
after or behind them. Nor shall they compass aught of His knowledge except
as He willeth. His Throne doth extend over the heavens and the earth, and
He feeleth no fatigue in guarding and preserving them for He is the Most
High, the Supreme (in glory).
PICKTHAL: Allah! There is no deity save Him, the Alive, the Eternal.
Neither slumber nor sleep overtaketh Him. Unto Him belongeth whatsoever is
in the heavens and whatsoever is in the earth. Who is he that intercedeth
with Him save by His leave? He knoweth that which is in front of them and
that which is behind them, while they encompass nothing of His knowledge
save what He will. His throne includeth the heavens and the earth, and He
is never weary of preserving them. He is the Sublime, the Tremendous.
SHAKIR: 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.
