Yahya related to me from Malik from Muhammad ibn Yahya ibn Habban from al Araj from Abu Hurayra that the Messenger of Allah, may Allah bless him and grant him peace, forbade prayer after asr until the sun had set, and prayer after subh until the sun had risen.
Muwatta Malik Book 15, Hadith 50
← Previous Hadith Yahya related to me from Malik from Nafi from Abdullah ibn Umar that the Messenger of Allah, may Allah bless him and grant him peace, said, "You should not intend to pray either at sunrise or sunset."

Muwatta Malik Book 15, Hadith 49 Next Hadith → Yahya related to me from Malik from Abdullah ibn Dinar from Abdullah ibn Umar that Umar ibn al-Khattab used to say, "Do not intend to do your prayer at either sunrise or sunset, for the horns of Shaytan rise with the rising of the sun and set with its setting."

Umar used to beat people for that kind of prayer.
