Amir bin Sa'd reported on the authority of his father (RA) that Allah's Messenger ( صلی اللہ علیہ وسلم ) said: I have declared sacred the territory between the two lava plains of Madinah, so its trees should not be cut down, or its game killed; and he also said: Madinah 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.
