Fuṣṣilat (Arabic: فصلت, fuṣṣilat [1] "are distinctly explained" or "explained in detail"), also known as Sūrat Ḥā Mīm as-Sajdah (Arabic: سورة ﺣﻢ ﺍﻟﺴﺠﺪﺓ),[2] is the 41st chapter (surah) of the Qur'an with 54 verses (āyāt).

Regarding the timing and contextual background of the revelation (asbāb al-nuzūl), it is traditionally believed to be a Meccan surah, from the second Meccan period (615-619).

Regarding Revelation in Islam (Waḥy) The word awha (أوحى awḥá) occurs in a number of shades of meaning in the Quran, each of them indicating the main underlying idea of directing or guiding someone or something.

For example, "And inspired in each heaven its command" (Fussilat-12).

Translator Sam Gerrans notes that the use of waḥī and awḥā throughout the Quran contains an element of the imperative, and thus translates: "And instructed each heaven in its command".
