1. A number of our people have narrated from Ahmad ibn Muhammad from ibn Faddal from Tha’labah ibn Mayamun from Yahya ibn Zakariya from abu ‘Ubaydah who has said the following: “’Ubaydah has said, ‘Once I was a partner of abu Ja’far (a.s.) on a journey. During the journey, first I would take my seat in the carriage set up on the back of the carry animal and then he would take his seat. He after settling down on his place properly would offer me the greeting of peace and ask a question like a person who has never met the other person. He would also shake hands. ’ The narrator has said, ‘He after dismounting would do so before me and after finding our places on the ground he would offer the greeting of peace and ask questions like he had never met me.’ 1 then said, ‘O descendent of the Messenger of Allah, you do things that no one before us has done. Doing (such formalities) only once is more than enough.’ The Imam asked, ‘Do you know what is in a handshake? The believers meet and shake hands, the sins continue falling off of them just like leaves fall off the trees, and Allah looks upon them until they depart from each other.’”

2. It is narrated from him (narrator of the Hadith above) from ibn Faddal from Ali ibn ‘Uqbah from Abu Khalid al-Qammat from Abu Ja’far (a.s.) who has said the following: "When the believing people meet and shake hands Allah inserts His hand between their hands and shakes hands with the one whose love for his brother (in belief) is more intense.’”

3. Ibn Faddal has narrated from Ali ibn ‘Uqbah from Ayyub from al-Sumayda’ from Malik ibn ‘A’Yun al-Juhni from abu Ja’far (a.s.) who has said the following: ‘When two believing people meet and shake hands Allah, the Most Majestic, the Most Holy, inserts His hand between their hands and faces the one whose love for his brother (in belief) is more intense. When Allah, the Most Majestic, the Most Holy, turns His face to them their sins begin to fall like leaves from trees.’”
