about a person who denies the punishment in the grave, because the reports in this regard are
Hadith-ul-Ahad (Hadiths which at some point in the chain have only a single narrator) which -they hold- can never be taken as basis for beliefs? They do not judge reports in terms of authenticity, acceptability, and weakness, but in terms of the numerous chains of transmission; whether it is a singular report or recurrently reported at each generation of narrators. Upon finding out that a certain report is singular, they reject it. How does one respond to this?
All Praise is due to Allah Alone. Peace and blessings be upon His Messenger, his family, and Companions. To commence, if a singular report is authentically reported from Allah's Messenger (peace be upon him), it is a credited proof according to the consensus of Ahl-ul-Sunnah wal-Jama`ah (those adhering to the Sunnah and the Muslim community), whether on issues of worship or creed. Whoever denies the authority of Hadith-ul-Ahad after establishing the evidence against him is a disbeliever. For further explanation in this regard, refer to the book entitled Al-Sawa`iq, by
Ibn Al-Qayyim or its abridged version by
Al-Mawsily. May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
