Muhammad b. Muhammad b. `Isam al-Kulayni narrated to us. He said: Muhammad b. Ya`qub al-Kulayni narrated to us from `Ali b. Muhammad from Muhammad b. Sulayman from Isma`il b. Ibrahim from Ja`far b. Muhammad al-Tamimi from al-Husayn b. `Ilwan from Abi `Abdillah al-Sadiq Ja`far b. Muhammad from his forefathers . He said:

The Messenger of Allah (s) said: There is not a believing man nor woman who has passed from the beginning of time till the Day of Resurrection except that they are an intercessor for those they mentioned in their supplication: “O Allah! Forgive the believing men and women.” A believer will be ordered to the Fire on the Day of Resurrection, but the believing men and women will say: “O our Lord! This is one who would pray for us, so accept our intercession for him.” So, Allah will accept their intercession and they will be saved.
