The testimony of one man alone

It is narrated from Amir that the Prophet (peace and blessings be upon him) accepted the testimony of Sayyiduna Khuzaymah bin Thabit (may Allah be pleased with him) as equal to that of two persons.

Abu Mijlaz said: I testified alone before Zurarah bin Awfa, and he accepted my testimony. What he did was very bad.

Abu Ishaq (may Allah have mercy on him) said: I testified alone before Shurayh, and he accepted my testimony.

Abu Ishaq said: Shurayh said to me: Do you testify that this is your handwriting, by your own hand, and that Razin dictated it to you? I said: Yes. So he accepted my testimony alone.

Shurayh accepted the testimony of one man concerning a copy of the Qur'an (mushaf).

Shurayh accepted the testimony of one man.
