22. Muhammad ibn Yahya has narrated from Bunan ibn Muhammad from his brother Ibrahim ibn Muhammad from Muhammad ibn ‘Isma‘il who has said the following: “I once sent a certain amount of dirham that belonged to me and someone else to abu al-Hassan, al- Rida’ عليه السلام, and wrote to inform him that it is of al-Fitrah of the family. He (the Imam) wrote with his hand writing, ‘I received and accepted.’”
