The Prophet Muhammad's Response to Aisha

Sahih al-Bukhari 3821: > Once Hala bint Khuwailid, Khadija's sister, asked the permission of > the Prophet to enter. On that, the Prophet remembered the way Khadija > used to ask permission, and that upset him. He said, "O Allah! Hala!" > So I became jealous and said, "What makes you remember an old woman > amongst the old women of Quraish an old woman (with a teethless mouth) > of red gums who died long ago, and in whose place Allah has given you > somebody better than her?" This website has the response of the Prophet Muhammad (peace and blessings be upon him): > "Allah did not give me someone in her place. She believed in me when > people denied me, she believed me, when people did not, she supported > me with her money, when people deprived me, Allah has blessed me with > her children and deprived me of the children of people." The website quotes that: Musnad Imam Ahmad 41/356 No. 24864, the verfiers of Hadith graded it as authentic. Is it the case that Bukhari or Muslim do not have the response of the Prophet Muhammad, or that I cannot find it? (Several website has given the further comment of Aisha, that with respect to Khadija, she kept quite after that incident.)
