It is narrated from Sayyiduna Anas bin Malik (may Allah be pleased with him): I said: O Messenger of Allah, where should I place my gaze in prayer? He (peace and blessings be upon him) said: "O Anas, keep your gaze on the place of your prostration." I said: O Messenger of Allah, this is difficult; I cannot do this. He (peace and blessings be upon him) said: "Then do so in the obligatory prayer."
Al-Rabi' bin Badr is da'if (weak), and what has preceded is sufficient.
