“Ja‘far ibn ‘Isa wrote to him (the Imam) (a.s.), and asked this question. ‘I pray to Allah to keep my soul in service for your cause. Our neighbor has brought to me a document thinking that they had appointed me as a witness for the case; in the document in which there is my name in my handwriting which I have recognized. However, I do not remember my witnessing the case; can I testify to my recognizing that my name is in the document, even though I do not remember my witnessing the case, or is it that testifying is not obligatory unless I remember witnessing the case, regardless, my name is in the document or not?’ He (the Imam) wrote the answer that said, ‘Do not testify.’”
