Sahih al-Bukhari Book 9, Hadith 58
Ibn `Umar said, "Allah's Messenger (ﷺ) said, 'Do not pray at the time of sunrise and at the time of sunset.' "
Ibn `Umar said, "Allah's Messenger (ﷺ) said, 'If the edge of the sun appears (above the horizon) delay the
prayer till it becomes high, and if the edge of the sun disappears, delay the prayer till it sets
(disappears completely).' "
"The Prophet (ﷺ) forbade praying after the Fajr prayer till the sun rises and after the `Asr prayer till the sun sets."
Narrated Ibn `Abbas:
Some people told me the same narration (as above).
Allah's Messenger (ﷺ) forbade two kinds of sales, two kinds of dresses, and two prayers. He forbade offering prayers after the Fajr prayer till the rising of the sun and after the `Asr prayer till its setting. He also forbade "Ishtimal-Assama " and "al-Ihtiba" in one garment in such a way that one's private parts are exposed towards the sky. He also forbade the sales called "Munabadha" and "Mulamasa." (See Hadith No. 354 and 355 Vol. 3).
