Is the grave of Halimah al-Sa'diyah in Zubair cemetery in Basra, and how did she get there?

Basra is one of the cities founded by Muslims during the era of Umar, may Allah be pleased with him. It is unlikely that there was a graveyard there at the time of Halimah's death, due to Halimah's distance from Basra. The dwellings of Bani Sa'd were close to Mecca. Therefore, what some writers have attributed to Ibn Battuta, that her grave is located in Basra, is far-fetched.
