Sayyiduna Salamah bin al-Akwa' (may Allah be pleased with him) said: I used to travel with the Prophet (peace and blessings be upon him), and I never once saw him (peace and blessings be upon him) offer any prayer after Asr or after the Fajr prayer.
Ahmad, and al-Tabarani in al-Mu'jam al-Awsat, recorded it, and Ahmad's narrators are the narrators of the Sahih.
