Sunan an-Nasa'i, Volume 1, Book 6, Hadith 562 (DarusSalam)

It was narrated from Abu Hurairah that the Prophet forbade praying after 'Asr until the sun had set, and after Subh until the sun had risen.

أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ مُحَمَّدِ بْنِ يَحْيَى بْنِ حِبَّانَ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم نَهَى عَنِ الصَّلاَةِ بَعْدَ الْعَصْرِ حَتَّى تَغْرُبَ الشَّمْسُ وَعَنِ الصَّلاَةِ بَعْدَ الصُّبْحِ حَتَّى تَطْلُعَ الشَّمْسُ ‏.‏
