It is narrated from Sayyidina Mu'adh bin Anas that a man asked the Prophet (peace and blessings be upon him): "Which jihad has the greatest reward?" The Prophet (peace and blessings be upon him) replied: "The one in which Allah is remembered the most." The questioner asked: "Which fasting people have the greatest reward?" The Prophet (peace and blessings be upon him) replied: "Those who remember Allah the most." Then the mention of prayer, Hajj, and Zakat came, and each time the Prophet (peace and blessings be upon him) said: "The one in which Allah is remembered the most." Upon this, Sayyidina Abu Bakr al-Siddiq and Sayyidina Umar began to say to each other: "O Abu Hafs, those who remember (Allah) have taken all the good." The Prophet (peace and blessings be upon him) said: "Yes."
