Abu Abdullah (asws) has said: ‘I (asws) was in the presence of Abu Ja’far, meaning Abu Al-Dawaniq, when a packet came and he opened it and looked inside it. So he took something out from it. He said, ‘O Abu Abdullah (asws), do you (asws) know what this is?’ I (asws) said: ‘What is it?’ He said, ‘This is something that has come to me from behind Africa, from Tanjat, (or Tabnat, Muhammad (the narrator doubted). So I (asws) said: ‘What is it?’ He said, ‘There is a mountain there from which drops come out in a year and solidify, and it is best for the whiteness which occurs in the eyes, if this is applied to them, it would go away by the Permission of Allah (azwj) Mighty and Majestic. I (asws) said, ‘Yes, I recognise it, and if you like I can inform you of its name and its condition’. He (asws) said: ‘He never asked me (asws) about its name’. He said, ‘And what is its condition?’ So I (asws) said: ‘This is a mountain on which was a Prophet (as) from the sons of the Children of Israel, who had fled from his (as) people, and he (as) used to worship upon it. So the people came to know about it, and they killed him. So it (mountain) now weeps over that Prophet (as), and these are the drops from its weeping. And on the other side of it is a spring from which the water flows by the night and the day, but it does not arrive to that fountain (of tears)’.
