ما هو شرح "بلغوا عني ولو آية"؟

The paragraph in question is part of an authentic Hadith, and its meaning is that a Muslim is required to convey what has reached him of the Quran and the Prophetic Ahadith to those whom it has not reached. The Hadith has been interpreted to mean that "even if it is one verse" refers to beneficial statements such as "whoever is silent is saved," or "religion is advice"; so the meaning becomes: Convey from me Ahadith, even if they are few. The first opinion is the most correct.
