Hazrat Abu Abdur Rahman says that I asked my father, Imam Ahmad (may Allah have mercy on him), that someone says whoever performs two rak'ahs in the mosque after Maghrib, it is not permissible unless he performs them at home, because the Noble Prophet (peace and blessings be upon him) said: "This is among the prayers of the home." He asked, "Who says this?" I replied, "Muhammad bin Abdur Rahman." He said, "He has spoken well."
