Hadith 31-202

حَدَّثَنا الحُسَيْنِ بْنِ أَحْمَدِ بْنِ إِدْرِيس‏ رَضِىَ اللهُ عَنْهُ قالَ: حَدَّثَنا أَبي، عَنْ جَعْفَرِ بْنِ مالِكَ الكُوفِيّ، قالَ: حَدَّثَني مُحَمَّد بْنِ أحْمَد المَدائِنيّ، عَنْ فَضْلِ بْنِ كَثِيرٍ، عَنْ عَلِىِّ بْن مُوسَى الرِّضا عَلَيْهِ السَّلامُ قالَ: مَن لَقيَ فَقيراً مُسلِماً فَسَلِّمَ عَلَيْهِ خِلافً سَلامِه عَلَى الأَغنِياءِ لَقِيَ اللَّه عَزَّ وَجَلَّ يَوْمَ القِيامَةِ وَهُوَعَلَيْهِ غَضْبان.

Al-Husayn ibn Ahmad ibn Idris - may God be pleased with him - narrated that his father quoted on the authority of Abi Ja’far Muhammad ibn Muhammad ibn Malik al-Kufi, on the authority of Muhammad ibn Ahmad al-Mada’eni, on the authority of Fadhl ibn Kathir that Ali ibn Musa Ar-Ridha’ (a.s.) said, "Whoever sees a poor person and greets him in a manner different from that with which he greets a rich man will visit God on the Resurrection Day while God is angry with him."
