Hadith on Love: Which handle of Islam is most reliable?

Al-Bara’ ibn ‘Azib reported: We were sitting with the Prophet, peace and blessings be upon him, and he said, “Which handle of Islam is the most trustworthy?” They said, “Prayer.” The Prophet said, “It is good, but that is not it.” They said, “Charity.” The Prophet said, “It is good, but that is not it.” They said, “Fasting the month of Ramadan.” The Prophet said, “It is good, but that is not it.” They said, “The Hajj pilgrimage.” The Prophet said, “It is good, but that is not it.” They said, “Jihad.” The Prophet said, “It is good, but that is not it. Verily, the most trustworthy handle of faith is to love and hate for the sake of Allah.
