Encouragement to live in Madinah

Sayyiduna Jabir (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) said: "A time will come upon the people of Madinah when people will leave it for various regions, seeking prosperity, and they will find prosperity. Then they will come and take their families away with them to that prosperity, although Madinah would have been better for them, if only they knew."
Imam Ahmad and Imam al-Bazzar recorded it; the narrators of al-Bazzar are the narrators of the Sahih.

Aflah, the freed slave of Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him), narrates that he passed by Sayyiduna Zayd bin Thabit (may Allah be pleased with him) and Sayyiduna Abu Ayyub al-Ansari (may Allah be pleased with him), and the two of them were seated at the Mosque of the Funerals. One of them said to the other: "Do you remember the hadith which the Messenger of Allah narrated to us in this mosque in which we are now present?" The other replied: "Yes! It was about Madinah. I heard him say: 'Soon a time will come upon the people in which various parts of the earth will be conquered for them, and people will go out to those regions. There they will find prosperity, comfort and food and drink. Then, on their way to Hajj or Umrah, they will pass by their brothers and say: "Why do you stay in this hardship of life and severe hunger?"' The Prophet (peace and blessings be upon him) said: 'So some will leave and some will stay' - he said this several times - (and then he said:) 'Madinah is better for them. Whoever remains here, patiently bearing its hardship and severity until he dies, I will be a witness for him on the Day of Resurrection (the narrator is in doubt; perhaps the words are:) an intercessor for him.'"
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir, and its narrators are thiqat (trustworthy).

Sayyiduna Abu Usayd al-Sa'idi (may Allah be pleased with him) narrates: I was present with the Prophet (peace and blessings be upon him) at the grave (that is, the body) of Sayyiduna Hamzah bin Abd al-Muttalib (may Allah be pleased with him). The people would pull the sheet over his face and his feet would become uncovered; they would pull the sheet over his feet and his face would become uncovered. The Prophet (peace and blessings be upon him) said: "Put this sheet over his face and place (the leaves of) this tree over his feet." The narrator says: Then the Prophet (peace and blessings be upon him) raised his head, and his Companions were weeping. The Prophet (peace and blessings be upon him) said: "A time will come upon the people when they will go out to fertile regions and there they will find food, clothing and mounts (the narrator is in doubt about one word here). Then they will write to their families: 'Come to us, for the land of the Hijaz is a land of drought,' although Madinah will be better for them, if only they knew."
Imam al-Tabarani recorded it in al-Mu'jam al-Kabir, and its chain is hasan (good).
