Hazrat Mu'adh Qureshi narrates that I performed Tawaf of the Ka'bah after Asr and after Fajr with Hazrat Mu'adh bin 'Afra. But I did not offer prayer. I asked him about this, and he said that the Prophet (peace and blessings be upon him) said: "There is no prayer after two prayers: after Fajr until the sun rises, and after Asr until the sun sets."
