Hadith #9

9- أَحْمَدُ عَنْ عَلِيِّ بْنِ أَسْبَاطٍ عَنْ بَعْضِ أَصْحَابِنَا عَنْ أَبِي عَبْدِ اللهِ (عَلَيْهِ السَّلام) قَالَ مَا كَانَ فِي شِيعَتِنَا فَلَمْ يَكُنْ فِيهِمْ ثَلاثَةُ أَشْيَاءَ مَنْ يَسْأَلُ فِي كَفِّهِ وَلَمْ يَكُنْ فِيهِمْ أَزْرَقُ أَخْضَرُ وَلَمْ يَكُنْ فِيهِمْ مَنْ يُؤْتَى فِي دُبُرِهِ.

9. Ahmad has narrated from Ali ibn Asbat from certain persons of our people who have said the following: “Abu ‘Abd Allah, ‘Alayhi al-Salam, has said, ‘Things may exist in our Shi‘ah, but three things will not be in them, one who stretches his hand for begging, there is no blue or green among them and one who allows sexual intercourse in his anus.’”
