Hadith 6685ـ مُحَمَّدُ بْنُ يَحْيَى عَنِ الْعَمْرَكِيِّ بْنِ عَلِيٍّ عَنْ عَلِيِّ بْنِ جَعْفَرٍ عَنْ أَبِي الْحَسَنِ (عَلَيهِ السَّلام) قَالَ مَنْ قَبَّلَ لِلرَّحِمِ ذَا قَرَابَةٍ فَلَيْسَ عَلَيْهِ شَيْءٌ وَقُبْلَةُ الأخِ عَلَى الْخَدِّ وَقُبْلَةُ الإمَامِ بَيْنَ عَيْنَيْهِ.
5. Muhammad ibn Yahya has narrated from al-‘Amraki ibn Ali ibn Ja’far from abu al-Hassan (a.s.) who has said the following: “Whoever of the relatives kisses a relative out of compassion he has not committed any offense. A brother may kiss the cheek of his brother. Kissing an Imam is between his eyes.”
