Is testimony admissible if the witness gains the requisite qualifications (such as justice or Islam) after witnessing the event but before giving testimony?

Primary text

The testimony of a witness is accepted if they witness an event (or hear it) while lacking the necessary qualifications, such as being a transgressor (*fasik*) or a disbeliever (*kafir*), and subsequently attain those qualifications (justice or Islam) before testifying. This is accepted without known dispute. This mirrors the rule regarding transmission of knowledge (*riwayah*), where competence is not required at the time of receiving knowledge but at the time of transmission. This principle is evidenced by the fact that children who heard the Prophet (peace be upon him) narrated Hadith after they grew up, such as Al-Hasan, Al-Husayn, Ibn Abbas, and others. Since testimony is akin to transmission, the legal requirements for giving testimony must be met at the time of performance (*ada*).
