Al-Hasan ibn Mahbub, from Umar ibn Yazid, who said: I (narrator) asked Abu Abdillah عليه السلام, peace be upon him, about ‘a man who has a guest with him from among his brothers, and the day of al-Fitrah arrives. Does he pay the fitrah on his behalf?’ Imam عليه السلام said: “Yes. The fitrah is obligatory upon everyone whom he supports, male or female, free or owned, young or old.” He (narrator) said: “And I asked Imam عليه السلام, ‘May he give the fitrah as flour in place of wheat?’” Imam عليه السلام said: “There is no harm. The cost of its grinding is according to the amount between the wheat and the flour.” He (narrator) said: “And I asked Imam عليه السلام, ‘May a man give the fitrah as dirhams, the price of dates and wheat, when that would be more beneficial for the household of the believer?’” Imam عليه السلام said: “There is no harm.”
