Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ قَالَ عَلَيْهِ اَلسَّلاَمُ: «بَادِرُوا بِالسَّلاَمِ عَلَى اَلْحَاجِّ وَ اَلْمُعْتَمِرِينَ وَ مُصَافَحَتِهِمْ مِنْ قَبْلِ أَنْ تُخَالِطَهُمُ اَلذُّنُوبُ ».
Imam عليه السلام said: "Hasten to greet the pilgrims and those performing Umrah and to shake their hands before sins mingle with them."
