However, a soil that contains such a cure must not be stored like this, lest it loses its effect. If one can ensure its protection then one should touch it to ones body or consume it, one shall be cured at once. Turbah is just like Hajar al-Aswad (the black stone) that used to glow like a white ruby and any diseased person who touched it used to be cured. Due to the infidels and the people of Jahiliyya touching it often, it became black and its effect lessened.
I asked, ‘How should we pick up the respected turbah? And how should we store it?’ Imam (a.s.) said, ‘You also pick up the turbah like other people and without wrapping it up in anything you keep it in your dirty bag. In this way it loses its barakat’. ‘You are right, Master,’ I said.
Then he said, ‘How would you take it if I were to give you a little bit of Turbah?’ I said that I shall keep it between the layers of my clothes and carry it away.’ Imam (a.s.) said, ‘When you return you may drink as much Sherbet as you like but do not take any Turbah with you because you will not be able to take care of it’ Before I left, Imam (a.s.) gave me the same sherbet twice.
After that I never suffered from the disease again.[^1] Keeping Turbah with the corpse There was an adulteress who used to destroy her illegitimate issues by putting them in the oven for fear of her family members. Except for her mother no one knew of her misdeeds. When she died and people tried to bury her, the earth did not accept her and threw her out. When they tried to bury her at another place the same thing happened.
The problem was presented to Imam Ja’far as-Sadiq (a.s.) and he asked her mother which sin she had committed. When the mother confessed, Imam (a.s.) said that earth would never accept her because she used to punish Allah’s creatures with the punishment that only Allah has the right to punish (That is, burning alive). Then Imam (a.s.) told them to place a little turbah in her grave.
This was done and then the earth did not convulse when she was buried in it.[^2] Anointing the Corpse with Turbah A little bit of Turbah should be placed on the face of the corpse when it is buried, it is Mustahab. It is also Mustahab to mix a little Turbah in the camphor which is applied to the corpse. However, it should only be used for anointing the forehead and palms. The knees and toes must be anointed only with camphor.
Because applying Turbah to the knees and toes would be an act of disrespect to it.
