وَ رَوَى اَلْحَسَنُ بْنُ مَحْبُوبٍ عَنْ هِشَامِ بْنِ سَالِمٍ عَنْ عَمَّارِ بْنِ مَرْوَانَ قَالَ سَأَلْتُ أَبَا عَبْدِ اَللَّهِ عَلَيْهِ اَلسَّلاَمُ أَوْ قَالَ سَأَلَهُ بَعْضُ أَصْحَابِهِ: عَنِ اَلرَّجُلِ يَشْهَدُ لِأَبِيهِ أَوِ اَلْأَخِ لِأَخِيهِ أَوِ اَلرَّجُلِ لاِمْرَأَتِهِ قَالَ "لاَ بَأْسَ بِذَلِكَ إِذَا كَانَ خَيِّراً تُقْبَلُ شَهَادَتُهُ لِأَبِيهِ وَ اَلْأَبِ لاِبْنِهِ وَ اَلْأَخِ لِأَخِيهِ".
And Al-Hasan ibn Mahbub narrated from Hisham ibn Salim, from Ammar ibn Marwan, who said: I asked Abu Abdullah (a.s), or it is said that one of his companions asked him, regarding a man who testifies in favor of his father, or a brother for his brother, or a man for his wife. Imam (a.s) said: "There is no harm in that if he is righteous. His testimony is accepted for his father, and a father's testimony is accepted for his son, and a brother's testimony is accepted for his brother."
