Sayyiduna Abu Hurairah, may Allah be pleased with him, narrates this statement of the Prophet Muhammad, peace and blessings be upon him: "Whoever catches one rak'ah of the 'Asr prayer before the sun sets has caught that prayer, and whoever catches one rak'ah of the Fajr prayer before the sun rises and performs one rak'ah after the sun has risen, then he has caught that (Fajr) prayer."
