Chapter on the Virtue of Good Deeds
Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 1|Chapter 11
وَ قَالَ اَلصَّادِقُ عَلَيْهِ اَلسَّلاَمُ: «لَعَنَ اَللَّهُ قَاطِعِي سَبِيلِ اَلْمَعْرُوفِ» قِيلَ وَ مَا قَاطِعِي سَبِيلِ اَلْمَعْرُوفِ قَالَ «اَلرَّجُلُ يُصْنَعُ إِلَيْهِ اَلْمَعْرُوفُ فَيَكْفُرُهُ فَيَمْنَعُ صَاحِبَهُ مِنْ أَنْ يَصْنَعَ ذَلِكَ إِلَى غَيْرِهِ ».
Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said: "May Allah سبحانه وتعالى curse those who block the path of kindness." It was asked: "Who are those who block the path of kindness?" Imam عليه السلام replied: "A person to whom kindness is shown but denies it, thereby discouraging its doer from extending it to others."
