Scholarly Authentication
The label above is the grade most of these scholars gave, each scholar counted once — one dissenting opinion no longer speaks for all of them. If any scholar calls a narration fabricated, that verdict is shown instead, whatever the others say. When they judged only its chain of narrators (“Isnaad”), the label says “Sound chain”. Each scholar's own wording:
Al-AlbaniDaif
Shuaib Al ArnautDaif
Our source also lists this ruling under Muhammad Fouad Abd al-Baqi, the editor of the printed edition it was taken from. It is al-Albani's ruling printed again, so it is counted once.
