Sahl narrates from his father that a woman came to the Prophet Muhammad (peace and blessings be upon him) and said: O Messenger of Allah! My husband has gone out for jihad, and I used to pray following his lead and perform the good deeds that he used to do. Now, tell me of an act that will raise me to the level of his deeds until he returns. The Prophet (peace and blessings be upon him) said: Are you able to stand in prayer continuously without pause, fast without breaking, and remember Allah without showing any laziness until your husband returns? She said: O Messenger of Allah! I do not have the strength for such deeds. The Prophet (peace and blessings be upon him) said: By Him in Whose hand is my soul! Even if you had the strength for it, you would not reach even a tenth of your husband's deeds until he returns.
