Salam aleykum,
I have heard from different hadiths that the earth/dust of Karbala cures every aliment except deadly ones and I do believe that every earth/place has its own energy which affects the people living there.
Well, I had an idea in mind and I wanted to see if its advisable or something that should be refrained from. I think all of my turbahs are from Karbala soil and after I have used them for some time they get dirty, I usually take a knife and scrape off the dirty top layer of the turbah, the "dirty" layer is still mixed with large amounts of Karbala soil.
So I was thinking: is it allowed to mix this earth with planting earth in a pot and then for example grow herbs or vegetables from that mixed earth? That way the fruit of such earth is grown on/from Karbala soil and should contain the blessings of it the way I see it.
Is it okay to do this and has anyone done it before/know if the fruits has the benefits of the earth?
