It is narrated from Sayyiduna Abu Huraira, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, was asked: "Which prayer is the best after the obligatory prayers?" He, peace and blessings be upon him, replied: "Prayer at any time during the night." Then someone asked: "Which fasts are the best after those of Ramadan?" He, peace and blessings be upon him, replied: "The fasts of Allah’s month, which you call Muharram."
