1. Ali ibn Ibrahim has narrated from his father from Ali ibn Ma’Bad from ‘Ubayd Allah ibn ‘Abd Allah al-Wasiti from Drust ibn abu Mansur from abu Khalid who has said the following: “Abu ‘Abd Allah  has said, ‘If a group of forty people come together to pray and plead before Allah, the Most Majestic, the Most Holy, for help in a matter, Allah will accept their prayers. If they are not forty then four people can pray to Allah, the Most Majestic, the Most Holy, ten times still Allah will accept their prayer. If four people are not present, then one person can pray forty times. Allah the Most Majestic, the Almighty, will accept his prayer.’”
