Amir bin Sa`d · The Book of Pilgrimage

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…

" 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.

God forbid that I should return anything which Allah's Messenger (ﷺ) has given me as spoil, and refused to return anything to them.
