Allah said,

﴿ظˆظژظ…ظژط¢ ط£ظژظ…ظ’ط±ظڈظ†ظژط¢ ط¥ظگظ„ط§ظ‘ظژ ظˆظژط­ظگط¯ظژط©ظŒ ظƒظژظ„ظژظ…ظ’ط­ظچ ط¨ظگط§ظ„ظ’ط¨ظژطµظژط±ظگ ﴾

(And Our commandment is but one as the twinkling of an eye.) This is information about the execution of His will in His creation, just as He informed us the execution of His decree in them,

﴿ظˆظژظ…ظژط¢ ط£ظژظ…ظ’ط±ظڈظ†ظژط¢ ط¥ظگظ„ط§ظ‘ظژ ظˆظژط­ظگط¯ظژط©ظŒ﴾

(And Our commandment is but one) meaning, `We only command a thing once, without needing to repeat the command; and whatever We command comes to existence faster than the blinking of an eye without any delay, not even for an instant.' Allah said,

﴿ظˆظژظ„ظژظ‚ظژط¯ظ’ ط£ظژظ‡ظ’ظ„ظژظƒظ’ظ†ظژط¢ ط£ظژط´ظ’ظٹظژظ€ط¹ظژظƒظڈظ…ظ’﴾

(And indeed, We have destroyed your likes), i.e. the earlier nations who denied their Messengers,

﴿ظپظژظ‡ظژظ„ظ’ ظ…ظگظ† ظ…ظ‘ظڈط¯ظ‘ظژظƒظگط±ظچ﴾

(then is there any that will remember) meaning, is there any that will receive admonition by remembering the humiliation and torment that Allah decreed for them

﴿ظˆظژط­ظگظٹظ„ظژ ط¨ظژظٹظ’ظ†ظژظ‡ظڈظ…ظ’ ظˆظژط¨ظژظٹظ’ظ†ظژ ظ…ظژط§ ظٹظژط´ظ’طھظژظ‡ظڈظˆظ†ظژ ظƒظژظ…ظژط§ ظپظڈط¹ظگظ„ظژ ط¨ظگط£ظژط´ظ’ظٹظژظ€ط¹ظگظ‡ظگظ… ظ…ظ‘ظگظ† ظ‚ظژط¨ظ’ظ„ظڈ﴾

(And a barrier will be set between them and that which they desire, as was done in the past with the people of their kind.)(34:54) Allah's statement,

﴿ظˆظژظƒظڈظ„ظ‘ظڈ ط´ظژظ‰ظ’ط،ظچ ظپظژط¹ظژظ„ظڈظˆظ‡ظڈ ظپظگظ‰ ط§ظ„ط²ظ‘ظڈط¨ظڈط±ظگ ﴾

(And everything they have done is noted in Az-Zubur.) meaning, everything they did is recorded in the Books of Record entrusted to the angels, peace be upon them,

﴿ظˆظژظƒظڈظ„ظ‘ظڈ طµظژط؛ظگظٹط±ظچ ظˆظژظƒظژط¨ظگظٹط±ظچ﴾

(And everything, small and large,) meaning, of their actions,

﴿ظ…ظ‘ظڈط³ظ’طھظژط·ظژط±ظŒ﴾

(is written down.) everything that they do is recorded and written in their Record of deeds, which leave nothing, whether large or small, but it is recorded and counted. Imam Ahmad recorded that `A'ishah said that the Messenger of Allah said,

آ«ظٹظژط§ ط¹ظژط§ط¦ظگط´ظژط©ظڈ ط¥ظگظٹظ‘ظژط§ظƒظگ ظˆظژظ…ظڈط­ظژظ‚ظ‘ظژط±ظژط§طھظگ ط§ظ„ط°ظ‘ظڈظ†ظڈظˆط¨ظگطŒ ظپظژط¥ظگظ†ظ‘ظژ ظ„ظژظ‡ظژط§ ظ…ظگظ†ظژ ط§ظ„ظ„ظ‡ظگ ط·ظژط§ظ„ظگط¨ظ‹ط§آ»

(O `A'ishah! Beware of small sins, because there is someone assigned by Allah who records them.) An-Nasa'i and Ibn Majah also collected this Hadith.
