Mishkat al-Masabih 1043
Kuraib said that Ibn ‘Abbas, al-Miswar b. Makhrama and ‘Abd ar-Rahman b. al-Azhar sent him to ‘A’isha telling him to give her their greetings and ask her about the two rak'as after the afternoon prayer. He said that when he went to visit her and conveyed their message she told him to ask Umm Salama, so he came out to them and they sent him back to Umm Salama who said :
I heard the Prophet prohibiting them and afterwards saw him praying them. When he came in I sent the slavegirl to him telling her to say that Umm Salama sent this query, “Messenger of God, I heard you prohibiting these two, and I see you praying them.” He replied, “Daughter of Abu Umayya,* you have asked about the two rak'as after the afternoon prayer. Some people of ‘Abd Qais came and hindered me from praying the two rak'as which come after the noon prayer, so those are the two I have been praying.”

* Abu Umayya was Umm Salama’s father. Although the slavegirl conveyed the query, the reply is given as if addressed directly to Umm Salama.
