" None should nurse ill-will towards the people of Medina, or Allah will melt him in fire like the melting of lead or the dissolution of salt in water.
Sahih Muslim Book 15, Hadith 523
← Previous Hadith I have declared sacred the territory between the two lava plains of Medina, so its trees should not be cut down, or its game killed; and he also said: Medina is best for them if they knew. No one leaves it through dislike of it without Allah putting in it someone better than he in place of him; and no one will stay there in spite of its hardships and distress without my being an intercessor or witness on behalf of him on the Day of Resurrection.
