This Hadith is Hasan Sahih Gharib. [Abu 'Eisa said:] It has been reported from other routes that 'Aishah said: "I and the Messenger of Allah (ﷺ) would perform Ghusl using (water from) the same vessel." And the following statement is not mentioned in it: "He had hair reaching above his shoulders [and below his earlobes'."
It was only mentioned by 'Abdur-Rahman bin Abi Az-Zinad, and he is trustworthy, a Hafiz, and Malik bin Anas stated that he was trustworthy and ordered recording (Ahadith) from him.
