Reward of shaking hands

1. My father رحمه الله said: it was narrated to me by Sa’d b. Abdillah from Ahmad b. Abi Abdillah from Muhammad b. Ali b. Muhammad b. al-Fudhayl from Abi Hamzah from Abi Abdillah عليه السلام who said: “The reward of shaking hands with each other is equal to the reward of a soldier in the way of Allah.”
