What is the correct implication of “fa-tabayyanū” for hadith transmission?

Trustworthy Transmission, the Report of a Fāsiq, and Responsible Narration

• Do not treat news from a compromised source as probative before verification
• A fāsiq’s report is conclusively false even before investigation
• The verse necessarily requires multiple narrators for accepting reports
• The command to verify concerns legal testimony alone, not hadith
