Abu Huraira reported God's messenger as saying, "No one from among my people will endure the hardship and rigour of Medina without my being an intercessor on his behalf on the day of resurrection."
Sa‘d reported God’s messenger as saying, “I declare sacred the territory between the two lava plains of Medina, so that its large thorn trees may not be cut down, or its game killed.” He also said, “Medina is best for them if they only knew. No one leaves it through dislike of it without God putting in it someone better than he in place of him, and no one will remain there in spite of its hardship and distress without my being an intercessor (or witness) on his behalf on the day of resurrection."
He told that when the people saw the first fruits they brought them to the Prophet, and when he received them he said, "O God, bless us in our fruits; bless us in our city; bless us in our sa‘; and bless us in our mudd. O God, Abraham was Thy servant, friend and prophet, and I am Thy servant and prophet. He made supplication to Thee on behalf of Mecca, and I make on behalf of Medina the same supplication as he made on behalf of Mecca and as much again." He would then call to him the youngest child and give him those fruits.
We wrote down nothing on the authority of God’s messenger but the Qur’an and what this document contains. He reported God’s messenger as saying, “Medina is sacred from ‘Air to Thaur, ( This phrase has been much discussed. ‘Air is known as a hill at Medina and Thaur at Mecca. Because of the difficulty some have suggested that Uhud should be read instead of Thaur, but others feel that that is unjustifiable.) so if anyone produces an innovation in it, or gives protection to an innovator, the curse of God, the angels, and all men will rest upon him, and no repentance or ransom (Lane in his Lexicon gives a variety of meanings for this phrase, la yuqbal minhu sarf wald 'adl. The one used above seems the most suitable here) will be accepted from him. The protection granted by Muslims is one and must be respected by the humblest of them, so if anyone breaks a covenant made by a Muslim the curse of God, the angels, and all men will rest upon him and no repentance or ransom will be accepted from him. If anyone gives the rights of inheritance to people without the permission of his masters, (This is explained in relation to a slave who has been set free, for the rights of inheritance still belong to his master who set him free. Cf. Book 12, ch. 6, third tradition) the curse of God, the angels, and all men will rest upon him, and no repentance or ransom will be accepted from him.’’
Bukhari and Muslim. A version given by both of them says, “ If anyone makes a false claim to paternity or to being a client, the curse of God, the angels and all men will rest upon him, and no repentance or ransom will be accepted from him.”
