Chapter on Precaution in Giving Testimony
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 1|Chapter 31
وَ رُوِيَ عَنْ عَلِيِّ بْنِ سُوَيْدٍ قَالَ: قُلْتُ لِأَبِي اَلْحَسَنِ اَلْمَاضِي عَلَيْهِ اَلسَّلاَمُ يُشْهِدُنِي هَؤُلاَءِ عَلَى إِخْوَانِي قَالَ "نَعَمْ أَقِمِ اَلشَّهَادَةَ لَهُمْ وَ إِنْ خِفْتَ عَلَى أَخِيكَ ضَرَراً ".
It is narrated from Ali ibn Suwayd, who said: I said to Abu al-Hasan al-Madhi عليه السلام (Imam Musa ibn Jafar Al-Kadhim عليه السلام): "These people call me to testify against my brothers." Imam عليه السلام said: 'Yes, establish the testimony for them, even if you fear harm for your brother.'"
