Cases of distortion in our literary legacy: "May your right hand be smeared..."

It is related in Ash-Shifā:

It is narrated on the authority of Umm Sulaym al-Anšāri, the mother of Anas b. Mālik, that she said: “O Messenger of Allah, Allah is not shy from the truth. If a woman saw in her dream what a man saw, does she perform the purification wash or not?” Ā’isha came to me and said: “Shame on you! Does a woman dream of such?” Allah’s Messengerﷺ came to me and said: ((May your right hand be smeared with dust, O Ā’isha! From where is family resemblance?)).

 “May your right hand be smeared with dust!” was a common imprecation among the Arabs. It denotes that the one who says it desires that the person be unsuccessful or not attain good. [Ref. Lane’s Arabic English Lexicon] There have been attempts to negate the apparent curse. The English translation of Sahīh al-Bukhāri by Dr Muhammad Muhsin Khan renders the imprecation as: ((May your right hand be saved!)).
