question #1 Sahih Muslim 209b, Book 1, Hadith 417 : What is the significance of intercession in Islam, particularly in relation to family members who supported the Prophet?

I heard Abbas say: I said: Messenger of Allah, verily Abu Talib defended you and helped you; would it be beneficial for him? He (the Holy Prophet) said: Yes; I found him in the lowest part of the Fire and I brought him to the shallow part.
