Musnad Ahmed: Hadith 1573

The Messenger of Allah (ﷺ) said: “I declare sacred what is between the two lava field of Madinah, (and I forbid) cutting of its thorny shrubs or killing of its game." And he said: "Madinah is better for them, if only they knew, No one leaves it out of dislike for it but Allah will replace him with someone better than him, and no one bears its hardships and difficulties with patience, but I will intercede for him, or be a witness for him, on the Day of Resurrection."
