Shama-il Tirmidhi Chapter 042, Hadith Number 008 (288).

Abu Hurayrah Radhiyallahu anhu says: "Rasulullah sallallahu alayhi wasallam said: 'Deeds are presented (before Allah subhanahu wata'allah) on Mondays and Thursdays. I desire that my deeds be presented whilst I am fasting'".

Commentary
Making it possible for these to be easily accepted. The question may arise regarding the presenting of deeds. The gist of a hadeeth mentioned in Sahih Muslim show that deeds are presented daily in the morning and evenings. What is meant by the deeds being presented on Mondays and Thursday? The Muhaditheen sum both up in different ways. The easiest is that the deeds of the day and night are presented in details twice a day. The deeds of the night separately and the ones of the day separately. On Mondays and Thursdays they are presented briefly. The deeds of the whole year are summed up in Sha'baan and Laylatul Qadar and presented before Allah the Almighty. One benefit among the many benefits of presenting the deeds repeatedly are that the honour of the pious are made evident before the angels. The angels raised a question when Allah Ta'aala created humans, that 'You are creating such a being that will spread bloodshed and turmoil in the world'. Allah Ta'aala knows at every moment the deeds committed by every person, therefore it is not necessary that deeds be presented to Him.
