The Ummah’s acceptance of a Hadith is a sign of the Hadith’s authenticity
The Imams of Hadith have written that because of Talaqqi Bil Qubool, a Hadith is strengthened. ‘Allama Abu Abdullah Muhammad bin Jamaluddin (May Allah shower His mercy on him) has written:
Translation: A Hadith which the Ummah has accepted is sure to be rigorously authenticated (Sahih). (An Nikatu ‘Ala Muqaddima Ibn Salah Tambeeh)
‘Allama Ibn Salah has written at another place:
Translation: When a weakly authenticated Hadith is accepted by the Ummah, then it will be acted upon as is the authoritative opinion.
Imam Suyuti (May Allah shower His mercy on him) has written in Tadreeb Ur Rawi:
Translation: When people accept a Hadith, then it will be judged to be rigorously authenticated (Sahih) even though its chain of narration may not be rigorously authenticated. (Tadreeb ur Rawi Lis Suyuti Al Awwal Us Sahih)
Thus, if a Hadith reaches the status of Talaqqi Bil Qubool, talking about its reliability or unreliability and investigation about its narrators is entirely unnecessary. For this reason, the unreliability of some narrators will not affect the deductions drawn from this Hadith.
Imam Shamsuddin Sakhawi (May Allah shower His mercy on him) has written:
Translation: When the Ummah accepts a Weak Hadith, then as per the authoritative opinion, it will be acted upon, so much that it is of the status of a Mutawatir (frequently occurring) Hadith, which can abrogate the Nas Qata‘ee (the canonical proofs) (Fathul Mugheeth Sharhu Alfiyatil Hadith Fi Ma’arifati Man Tuqbalu Riwayatuhoo Wa Man Turaddu)
