Sayyidah Aishah Siddiqah (may Allah be pleased with her) says: The Prophet (peace and blessings be upon him) said to her: "Whoever has been given his share of gentleness has been given his share of the good of this world and the Hereafter. Looking after the rights of kinship, being a good neighbour and having good character make lands flourish and increase lifespans."
Ahmad recorded it, and its narrators are thiqat (trustworthy), except that Abd al-Rahman bin al-Qasim did not hear from Sayyidah Aishah (may Allah be pleased with her).
