question #1 Sahih Muslim 123b, Book 1, Hadith 231 : What is the significance of good deeds performed before accepting Islam in terms of their reward in the Hereafter?

Messenger of Allah, do you think if there is any reward (of the Lord with me on the Day of Resurrection) for the deeds of religious purification that I performed in the state of ignorance, such as charity, freeing a slave, cementing of blood-relations? Upon this he (the Messenger of Allah) said to him: You have accepted Islam with all the previous virtues that you had practised.
