The sun has passed its zenith (1).

This is a sound hadith (2).

‌‌6 - Chapter: What has been reported about delaying the noon prayer in severe heat

157 - Qutaybah narrated to us, saying: Al-Layth narrated to us, from Ibn Shihab, from Sa'id ibn al-Musayyab and Abu Salamah,
from Abu Hurayrah, who said: The Messenger of Allah, peace and blessings be upon him, said: "When the heat is intense, delay the prayer until it cools, for the intensity of heat is from the blast of Hell" (3).

(1) A sound hadith, also narrated by Ahmad (12643), al-Bukhari (540) and (7294), Muslim (2359) (136), al-Nasa'i 1/246-247, and Ibn Hibban (106) and (1502), with some of their narrations being longer.

(2) In the edition of Shaykh Ahmad Shakir, there is an addition here: "And it is the best hadith on this topic, and there is also a hadith on this topic from Jabir," but this is not found in any of our manuscript copies.

(3) A sound hadith, also narrated by al-Bukhari (533), Muslim (615), Abu Dawud (402), Ibn Majah (677) and (678), and al-Nasa'i 1/248-249, and it is in "al-Musnad" (7130) and "Sahih Ibn Hibban" (1506) and (1507).

Al-Khattabi said in "Ma'alim al-Sunan" 1/128-129: The meaning of "cooling" (ibrad) in this hadith is: the abatement of the intense heat of midday. And Muhammad ibn Ka'b al-Qurazi said: We would be on a journey, and when the shadows shifted and the breezes blew, they would say: "It has cooled — so set off."

And his saying, peace and blessings be upon him, "the blast of Hell" (fayh) means: the rising and spreading of its heat. Its origin in their speech is: spaciousness and spreading. From it comes their saying: "a spacious place" (maqan afyah), meaning wide, and "a wide land" (ard fayha'), meaning expansive. =
