There appears to be two different hadiths on praying after 'Asr.
Some hadiths say it is haram.
Narrated Abu Sa'id Al-Khudri: I heard Allah's Apostle saying, "There is no prayer after the morning prayer till the sun rises, and there is no prayer after the Asr prayer till the sun sets." (Bukhari Volume 1, Book 10, Number 560)
Allah's Apostle forbade the offering of two prayers: 1. after the morning prayer till the sunrises. 2. after the 'Asr prayer till the sun sets. (Bukhari Volume 1, Book 10, Number 562)
Some hadiths say it is highly encouraged.
'Aisha (addressing me) said, "O son of my sister! The Prophet never missed two prostrations (i.e. Rakat) after the 'Asr prayer in my house." (Volume 1, Book 10, Number 565)
Allah's Apostle never missed two Rakat before the Fajr prayer and after the Asr prayer openly and secretly. (Bukhari Volume 1, Book 10, Number 566)
Whenever the Prophet come to me after the 'Asr prayer, he always prayed two Rakat. (Bukhari Volume 1, Book 10, Number 567)
Am I misunderstanding this? Is it allowed/encouraged to pray after 'Asr?
