So it is...

So it is, from what the earth grows, but it is from the sand and the salt, and they have both been metamorphosed’. [4] Allah -azwj Blessed the dust of Karbala and Elevated its Status The dust of Karbala is the most blessed and sanctified earth, hence followers of Ahl Al-Byat ‑asws prefer to perform Sajdah on a tablet made out from the dust of Karbala.

See for example, three Ahadith reporting that Allah -azwj Decided to elevate and Bless the dust of Karbala when these humbled and submitted to the Will of the High and Exalted -azwj .

Abu Al-Abbas Al-Kufi told me on the authority of Muhammad ibn al-Husayn ibn Abi al-Khattab on the authority of Abi Saeed al-Asfari on the authority of Amr ibn Thabit, who from his father who said: Abi Jaffar -asws (Imam Mohammed Baqir -asws ) said: Allah -azwj Created, blessed and sanctified the land of Karbala twenty-four thousand years before He -azwj Created the Kabah.

Hence it was blessed and sanctified before the creation of any created being and it will remain this way until Allah -azwj Raises it to Paradise and appoints it as the best land in Paradise. It will be the best abode in Paradise in which Allah -azwj will Make His -azwj friends abide.
