The Intercession
The Intercession is true. It is to ask for the good from another for another; and so the Prophet and the practicing scholars and the martyrs and the angels will intercede. Our Prophet will intercede for the major sinners of his nation, and it came in the authentic hadith,
شَفَاعَتِي لأَهْلِ الكبَائرِ مِن أمَّتي
[which means] “My intercession is for the major sinners of my nation,” narrated by Ibn Hibban; meaning that other than the major sinners are not in need of intercession.
For some of them it would be before they enter Hell, and for some of them it would be after they enter Hell, but before the time that they deserve to be tortured passes. There will be no intercession for the blasphemers. Allah the Exalted Said,
﴿وَلَا يَشْفَعُونَ إِلَّا لِمَنِ ارْتَضَىٰ﴾
[which means] “They will not intercede for anyone except those who are accepted by Allah.” The first one to intercede is the Prophet.
