Is the name of Hz. Musa's sister Maryam or Kulthum?

Dear Brother / Sister,

In some resources, the name of Hz. Musa’s sister is mentioned as Maryam. (see Shawkani, Fathul-Qadir, al-Qasas, the interpretation of verse 28/12)

Accordingly, the name of Hz. Musa's sister is Maryam like Hz. Isa's mother.

According to the narration Mawardi makes from Dahhak, the name of Hz. Musa’s sister is Kalthama. As-Suhay­li says it is Kulthum. This is according to a hadith reported by Zubayr b. Bakkar. Accordingly, the Prophet said to Hz. Khadijah, "Along with you, Allah will marry Maryam, the daughter of Imran, Kulthum, the sister of Musa and Asiya, the wife of the Pharaoh, off to me." Hz. Khadijah asked, "Did Allah inform you about it?" The Prophet said, "Yes". Thereupon, Khadijah said, "May it be nice and good for you!" (Qurtubi, Ahkam, al-Qasas, the interpretation of verse 28/12)

Besides, in another hadith narration, though a weak one, the name of Hz. Musa’s sister is mentioned as Kulthum: “Allah decreed that Maryam, the daughter of Imran, Asiya, the wife of the Pharaoh and Kulthum, the sister of Musa, would be my wives in Paradise.” (Tabarani, al-Mu'jamul-Kabir, 8/258; Majmauz-Zawaid, 9/218)

See other tafsir resources regarding the issue. (e.g. Abu Hayyan, al-Bahrul-Muhit; Alusi, Ruhul-Maani, al-Qasas, the interpretation of verse 28/12)
