Question Summary:
Does Allah forgive a deceased person upon whom more than 200 people have offered Salatul Janaazah?

Question Detail:

Asalaamalaikum. Long time back in a bayaan I have heard that if more than 200 people pray salah behind a Janazah Allah (SWT) forgives all the sins of the dead person. Can you please clarify the same in reference to some Hadith. Jazak-Allah.

Answer :

In the Name of Allah, the Most Gracious, the Most Merciful.
As-salāmu ‘alaykum wa-rahmatullāhi wa-barakātuh.
There are numerous Ahadith in which the Prophet Salllallahu Alaihi Wa Sallam has mentioned that those who will perform Salahtul Janaazah upon a deceased person will also intercede on behalf of him.
مَا مِنْ رَجُلٍ مُسْلِمٍ يَمُوتُ، فَيَقُومُ عَلَى جَنَازَتِهِ أَرْبَعُونَ رَجُلًا، لَا يُشْرِكُونَ بِاللهِ شَيْئًا، إِلَّا شَفَّعَهُمُ اللهُ فِيهِ[1]
“There is no Muslim who passes away upon whom a group of forty people perform his Janaazah Salah who have not associated partners will Allah but that they will intercede on his (deceased person) behalf.”
مَا مِنْ مَيِّتٍ تُصَلِّي عَلَيْهِ أُمَّةٌ مِنَ الْمُسْلِمِينَ يَبْلُغُونَ مِائَةً، كُلُّهُمْ يَشْفَعُونَ لَهُ، إِلَّا شُفِّعُوا فِيهِ[2]
“There is no deceased person upon whom a group of hundred Muslims have performed Janaazah Salah, each one will intercede for him, but that he shall be interceded.”
