The Messenger of Allah ﷺ told us two hadiths. I have witnessed one of them, and I am waiting for the other. He then mentioned its meaning.
حدثنا وكيع حدثنا الأعمش عن زيد بن وهب
حدثنا رسول الله ﷺ حديثين رأيت أحدهما وأنا أنتظر الآخر فذكر معناه
Its isnad is sahih, and it is like the previous one. This is the route of Sahihayn.
