4. Ali ibn Ibrahim has narrated from his father from Ali ibn Ma’Bad from ‘Ubayd Allah ibn ‘Abd Allah al-Wasity from Durst ibn abu Mansur from abu Khalid al- Qammat who has said the following: “Abu Ja’far  has said, ‘The prayer quickest to success and acceptance is one’s prayer for his brother (in belief) in his absence where one starts praying for him and the angels guarding say, ‘Amin’ You will have twice as much you asked for him.’”
