Chapter on Oaths, Vows, and Expiations
Man Lā Yaḥḍuruh al-Faqīh|Volume 3|Book 2|Chapter 38
وَ سَأَلَ إِسْحَاقُ بْنُ عَمَّارٍ أَبَا إِبْرَاهِيمَ عَلَيْهِ اَلسَّلاَمُ: فَقَالَ يُعْطَى ضَعِيفاً مِنْ غَيْرِ أَهْلِ اَلْوَلاَيَةِ قَالَ "نَعَمْ وَ أَهْلُ اَلْوَلاَيَةِ أَحَبُّ إِلَيَّ ".
Ishaq ibn Ammar asked Abu Ibrahim (Imam Musa ibn Jafar Al-Kadhim عليه السلام) whether it is permissible to give expiation to someone who is weak but not from the people of wilayah (those who follow the Ahlulbayt). Imam عليه السلام said: "Yes, but the people of wilayah are more beloved to me."
