‘Abdallah b. Mas'ud reported God's messenger as saying, “If anyone comforts one who has been afflicted he will have a reward equivalent to his.”
Tirmidhi and Ibn Majah transmitted it, Tirmidhi saying this is a gharib tradition which was known to him as traced back to the Prophet only among the traditions of ‘Ali b. ‘Asim the transmitter. He added that some transmitted it with this isnad from Muhammad b. Suqa in mauquf form.
