8ـ عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ مُحَمَّدِ بْنِ عِيسَى عَنْ يُونُسَ بْنِ عَبْدِ الرَّحْمَنِ عَنْ عَبْدِ الاعْلَى عَنْ أَبِي عَبْدِ الله (عَلَيْهِ السَّلام) قَالَ إِنَّ أَبِي (عَلَيْهِ السَّلام) اسْتَوْدَعَنِي مَا هُنَاكَ فَلَمَّا حَضَرَتْهُ الْوَفَاةُ قَالَ ادْعُ لِي شُهُوداً فَدَعَوْتُ لَهُ أَرْبَعَةً مِنْ قُرَيْشٍ فِيهِمْ نَافِعٌ مَوْلَى عَبْدِ الله بْنِ عُمَرَ فَقَالَ اكْتُبْ هَذَا مَا أَوْصَى بِهِ يَعْقُوبُ بَنِيهِ يا بَنِيَّ إِنَّ الله اصْطَفى‏ لَكُمُ الدِّينَ فَلا تَمُوتُنَّ إِلا وَأَنْتُمْ مُسْلِمُونَ وَأَوْصَى مُحَمَّدُ بْنُ عَلِيٍّ إِلَى جَعْفَرِ بْنِ مُحَمَّدٍ وَأَمَرَهُ أَنْ يُكَفِّنَهُ فِي بُرْدِهِ الَّذِي كَانَ يُصَلِّي فِيهِ الْجُمُعَةَ وَأَنْ يُعَمِّمَهُ بِعِمَامَتِهِ وَأَنْ يُرَبِّعَ قَبْرَهُ وَيَرْفَعَهُ أَرْبَعَ أَصَابِعَ وَأَنْ يَحُلَّ عَنْهُ أَطْمَارَهُ عِنْدَ دَفْنِهِ ثُمَّ قَالَ لِلشُّهُودِ انْصَرِفُوا رَحِمَكُمُ الله فَقُلْتُ لَهُ يَا أَبَتِ بَعْدَ مَا انْصَرَفُوا مَا كَانَ فِي هَذَا بِأَنْ تُشْهِدَ عَلَيْهِ فَقَالَ يَا بُنَيَّ كَرِهْتُ أَنْ تُغْلَبَ وَأَنْ يُقَالَ إِنَّهُ لَمْ يُوصَ إِلَيْهِ فَأَرَدْتُ أَنْ تَكُونَ لَكَ الْحُجَّةُ.

8. Ali ibn Ibrahim has narrated from Muhammad ibn ‘Isa from Yunus ibn ‘Abd al-Rahman from ‘Abd al-A‘la from abu ‘Abdallah (a.s.) who has said the following. “My father entrusted me with all that is there (the sacred objects inherited from the prophets such as directive wills etc.). When he was about to leave this world, he asked me to call for him a few people to bear testimony. I then called for him four people from Quraysh among them was Nafi‘ Mawla ‘Abdallah ibn ‘Umar. He then said, “Write down: This is (like) what was the directive will of Jacob to his sons, “My sons, God has chosen this religion for you. You must not leave this world unless you are a Muslim (submitted to the will of the Lord of the Universe).” (2:132). Muhammad ibn Ali has recommended Ja‘far ibn Muhammad in his directive will and commands him to shroud him with his gown with which he would [erform his prayers on Fridays and prepare a turban for him out of his own turban. That he should shape his grave squirely and raise it four inches from the ground and open the knots of from all ends of his shroud when it is to bury him. Then he said to the testimony bearers, “You may go now, may Allah bless you.” I then asked him after they had left, “O father, you did not need to make a will for such matters.” He said, “My son, I did not like when you will be over come they would say, “No directive will was made in his favor.” I just wanted to establish a defence authority in your favor.”
