Ahmad bin Salih (may Allah have mercy on him) narrates the same, but with an addition: I said to Urwah (may Allah have mercy on him): Your brother (may Allah be pleased with him) did not pray more than two rak'ahs at the solar eclipse, like the Fajr prayer. He said: He forgot the Sunnah, or he made a mistake.
