Sayyiduna Abu Darda (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) delivered a sermon before us and said:“May Allah keep fresh the person who hears a hadith from us and conveys it exactly as he heard it (to others), because sometimes the one to whom the hadith is conveyed remembers it better than the one who heard it. There are three things regarding which the heart of a Muslim does not betray: making deeds sincere for Allah, wishing well for every Muslim, and adhering to the community of Muslims, for their prayers encompass them from behind.”
