Ismail bin Ubaidullah said: Whenever Sayyiduna Abu Darda (may Allah be pleased with him) narrated a hadith from the Messenger of Allah (peace and blessings be upon him), he would say: «قال كذا أو نحوه أو شبهه أو شكله» (that is, the Messenger of Allah [peace and blessings be upon him] said something like this, similar to this, or in this meaning).
