The name al-Humayrâ' refers to `A'ishah's light complexion.
There is hadîth evidence in Sunan al-Nasâ'î which establishes that the Prophet (peace be upon him) at least occasionally called `A'ishah by the nickname Humayrâ'.
One of these occasions is where `A'ishah was watching the Ethiopian acrobats in the in the performing mosque and the Prophet (peace be upon him) said: "O Humayrâ', do you wish to watch them?" [Sunan al-Nasâ'î al-Kubrâ' (5/307)]
This hadîth is authentic.
It is interesting to note that aside from this hadîth and one other in Sunan al-Nasâ'î, all other hadîth that refer to `A'ishah as "al-Humayrâ' " are false.
The eminent scholar of hadîth, al-Mizzî, said: "Every hadîth which mentions al-Humayrâ' is false, except for one hadîth about fasting found in Sunan al-Nasâ'î."
Ibn Kathîr – who was incidentally al-Mizzî's student – corrected this assessment by pointing out the other authentic hadîth in Sunan al-Nasâ'î regarding the acrobats.
And Allah knows best.
