Silsilat al-Ahadith al-Sahihah

It is narrated from Umm al-Mu'minin Sayyidah Aisha (may Allah be pleased with her) that the Prophet Muhammad (peace and blessings be upon him) said to her: "Whoever is granted gentleness, he has been given goodness and well-being of this world and the Hereafter. And maintaining ties of kinship, good character, and good treatment of neighbors (such good deeds) populate homes (and tribes) and increase lifespans."
