Basr bin Sa'id al-Madni بسر بن سعيد المدني العابد · The Book on Salat (Prayer)

the Prophet said: "Whoever catches a Rak'ah of Subh before the sun has risen, then he has caught Subh. Whoever catches a Rak'ah of Asr before the sun has set, then he has caught Asr."

that Allah's Messenger said: "If the one who passed in front of the person performing Salat knew what he was doing, then for him to stop (and wait for forty) would be better for him than to pass in front of him."

"I asked Aishah how the recitation of the Prophet (S) was at night. So she said: 'He would do both of those. Sometimes he was silent with his recitation and sometimes it was audible.' So I said: 'All praise is due to Allah, the One who made the matter broad.'"
