Silsilat al-Ahadith al-Sahihah

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