It is narrated from Sayyiduna Safwan bin Mu'attal Salmi (may Allah be pleased with him), he asked the Noble Prophet (peace and blessings be upon him) and said: O Messenger of Allah! I want to ask you about something which you know, but I do not know. The Prophet (peace and blessings be upon him) said: What is it? He said: Are there such hours during the day and night in which it is disliked to perform prayer? The Messenger of Allah (peace and blessings be upon him) said: Yes, when you have performed the Fajr prayer, then refrain from performing any more prayer until the sun rises. When the sun has risen, then perform prayer, for indeed that prayer is presented and accepted, until the sun is at the height of a spear above your head. When it is above your head, then at that time Hell is kindled and its doors are opened, until it declines from your right side. When it declines from your right side, then perform prayer, for the prayer at that time is presented and accepted, until you have performed the Asr prayer.
