It is narrated from al-Zubayr ibn al-'Awamm that Allah's Messenger said: "The disease of previous nations has crawled its way to you: envy and hatred. Hatred is the shearer (al-haliqa). It does not shear hair but it shears religion. By the One in Whose hand is Muhammad's soul! You shall never enter Paradise until you believe, and you shall never believe until you love one another. Shall I inform you of something which, if you do it, you shall love one another?" They said: "Yes, O Messenger of Allah!" He said: "Spread salaams among yourselves."
Allah's blessings and peace on the Prophet., his Family, and his Companions
