question #1 Sahih Muslim 835d, Book 6, Hadith 365 : What is the significance of performing additional prayers after the Asr prayer?

We bear testimony to the fact that ‘A’isha said: Never was there a day that he (the Holy Prophet) was with me and he did not observe two rak’ahs of prayer in my house, i. e. two rak’ahs after the Asr.
