Maʿānī al-ʾAkhbār > The meaning of the saying of Ali bin Hussain, peace be upon them both: «Woe to the one whose singulars overcome his tens»
Hadith #1

أبي - رحمه الله - قال: حدثنا سعد بن عبد الله، عن يعقوب بن يزيد، عن ابن أبي عمير، عن هشام بن سالم، عن أبي عبد الله عليه السلام قال: كان علي بن الحسين صلوات الله عليهما يقول: ويل لمن غلبت آحاده أعشار. فقلت له: وكيف هذا؟ فقال: أما سمعت الله عز وجل يقول: " من جاء بالحسنة فله عشر أمثالها ومن جاء بالسيئة فلا يجزي إلا مثلها " فالحسنة الواحدة إذا عملها كتبت له عشرا، والسيئة الواحدة إذا عملها كتبت له واحدة فنعوذ بالله ممن يرتكب في يوم واحد عشر سيئات ولا تكون له حسنة واحدة فتغلب حسناته سيئاته.

1. My father, may Allah grant him mercy, said: We were told by Sa’d bin Abdullah, from Ya’qoub bin Yazid, from Ibn Abi ‘Umayr, from Hisham bin Salem, from Abu Abdillah, peace be upon him, that he said: Ali bin Hussain, Allah’s blessings be upon them both, used to say: Woe to the one whose singulars overcome his tens. So I said to him: And how is that? He said: Have you not heard Allah, Exalted and Glorious is He, say: «The one who brings a good deed, to him is ten the like of it, and the one who brings a misdeed, he will not be rewarded except by the like of it» (6:160)? Hence, if one performs one good deed, ten will be written for him, and if one performs one misdeed, one will be written for him. Thus, we seek refuge in Allah from the one who performs, on one day, ten misdeeds and does not (even) have one good deed by which his good deeds can overcome his misdeeds.
