Is there any merit in the large number of people praying over the deceased (Janazah)?

It has been established in the prophetic tradition that if any Muslim dies, and forty men who do not associate partners with Allah pray over his funeral, Allah will accept their intercession for him. Therefore, it is preferable to choose a mosque with a large congregation for the funeral prayer, for the greater the number, the closer it is to goodness and the more prayers there will be.
