Bushayr bin Yasar (may Allah have mercy on him) narrates: I asked Sayyiduna Anas (may Allah be pleased with him): "Compared with the blessed time of the Messenger of Allah (peace and blessings be upon him), what do you find objectionable in our condition?" He said: "Indeed, you people do not complete the rows (in prayer)."
No one narrated this hadith from Bushayr bin Yasar except Uqbah bin Ubayd.
