Mukhtasar Bukhari

Narrated by Sayyiduna Ibn Abbas (may Allah be pleased with them both): Some beloved personalities mentioned before me, and the most beloved among them to me was the Commander of the Faithful, Umar (may Allah be pleased with him), stated that the Messenger of Allah (peace and blessings be upon him) forbade performing prayer after the Fajr prayer until the sun rises, and after the Asr prayer until the sun sets.

Narrated Ibn Umar (may Allah be pleased with them) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "(O people!) Do not perform your prayers at the time of sunrise nor at the time of sunset."

Narrated Ibn Umar (may Allah be pleased with them) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "When the edge of the sun appears, stop praying until the sun rises high, and when the edge of the sun sets, stop praying until (the whole sun) has set."

Narrated from Sayyiduna Abu Hurairah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) forbade two types of sales and two types of clothing (and this hadith has already been mentioned, see the Book: Description of Prayer... Chapter: Covering that which must be covered). In this hadith, it is further stated: "And he forbade two prayers: (1) He forbade prayer after Fajr until the sun rises properly, and (2) after Asr until the sun sets properly."
