Sayyiduna Abu Usayd (may Allah be pleased with him) narrates that he heard the Prophet (peace and blessings be upon him) say: "No prayer is to be offered after Asr."
Al-Tabarani recorded it in al-Mu'jam al-Kabir; its chain contains a narrator, Farwah bin Abi Farwah, and I have not found anyone who mentions him. The remaining narrators of this report are thiqat (trustworthy).
