“Three things — whoever brings them together has brought faith together: being fair even against yourself, offering the greeting of peace to everyone, and spending even when you have little.”

‘Ammar ibn Yasir (d. 37 AH / 657 CE) was among the earliest Muslims in Makkah, and his parents were among its first martyrs. Al-Bukhari quotes these words of his at the head of a chapter in the Book of Faith titled “spreading the greeting of peace is part of Islam.” They are ‘Ammar’s own words, cited without their chain, not a hadith of the Prophet (peace be upon him).
