2- عَلِيُّ بْنُ إِبْرَاهِيمَ عَنْ أَبِيهِ عَنِ الرَّيَّانِ بْنِ شَبِيبٍ قَالَ أَوْصَتْ مَارِدَةُ لِقَوْمٍ نَصَارَى فَرَّاشِينَ بِوَصِيَّةٍ فَقَالَ أَصْحَابُنَا اقْسِمْ هَذَا فِي فُقَرَاءِ الْمُؤْمِنِينَ مِنْ أَصْحَابِكَ فَسَأَلْتُ الرِّضَا (عَلَيْهِ السَّلام) فَقُلْتُ إِنَّ أُخْتِي أَوْصَتْ بِوَصِيَّةٍ لِقَوْمٍ نَصَارَى وَأَرَدْتُ أَنْ أَصْرِفَ ذَلِكَ إِلَى قَوْمٍ مِنْ أَصْحَابِنَا مُسْلِمِينَ فَقَالَ أَمْضِ الْوَصِيَّةَ عَلَى مَا أَوْصَتْ بِهِ قَالَ اللهُ تَبَارَكَ وَتَعَالَى فَإِنَّما إِثْمُهُ عَلَى الَّذِينَ يُبَدِّلُونَهُ.

2. Ali ibn Ibrahim has narrated from his father from al-Rayyan ibn Shabib who has narrated the following: “Maridah made a will for the Christians who worked as maintenance people. Our people said to spend it on the poor believers of your people. I then asked al-Rida’, ‘Alayhi al-Salam, that my sister has made a will for Christian persons and I wanted to spend it for our Muslim people. He (the Imam) said, ‘You must execute the will as you are required. Allah, most Blessed, most High, has said, “Whoever intentionally changes the will of a deceased person, he has committed a sin. Allah is All-hearing and All-knowing.” (2:181)”’
