Silsilat al-Ahadith al-Sahihah

Sahl bin Mu’adh bin Anas narrates from his father that a woman came to the Prophet (peace and blessings of Allah be upon him) and said: O Messenger of Allah! My husband has gone out for jihad, and I used to follow him in prayer and all his (good) deeds. Now, tell me of an act that will make me reach the level of his deeds. The Prophet (peace and blessings of Allah be upon him) said to her: “Are you able to stand (in prayer) continuously without resting, and to fast continuously without breaking your fast, and to remember Allah continuously without ever being heedless, until he returns?” She said: O Messenger of Allah! I do not have the strength for this action. The Prophet (peace and blessings of Allah be upon him) said: “Even if you were able to do these deeds, you would not reach even a tenth of his deeds.”
