Ibrahim bin Mahziyar wrote to Abu Muhammad al-Hasan (a.

Ibrahim bin Mahziyar wrote to Abu Muhammad al-Hasan (a.s.) asking him about offering prayer in (clothes dyed with) kermes and saying that his companions refrained from offering the prayer in it. Imam Abu Muhammad (a.s.) replied, ‘There is no problem in it at all, and praise be to Allah.’[^158] Muhammad bin al-Hasan as-Saffar wrote To Imam Abu Muhammad al-Hasan bin Ali (a.s.) asking him, ‘Some man died and he had ten days of qadha’[^159] fasting that he had to perform before his death.

He left two successors (children). Is it possible for each one of his successors to fast for five days?’ The imam (a.s.) replied, ‘His elder successor is to fast for ten days, inshallah.’[^160] Ibrahim bin Mahziyar wrote to Imam Abu Muhammad (a.s.): “O my master, your mawla[^161] Ali bin Mahziyar had recommended the hajj to be performed on behalf of him from (the revenue of) a garden…twenty dinars every years, and since the way of Basra was blocked, costs became doubled for people that twenty dinars were not enough (for the hajj).

Some others of your mawlas recommended of two (performances of) hajj.’ The imam (a.s.) replied, ‘You make (the costs of) three seasons of hajj in two, inshallah the Almighty.’[^162] Ali bin Muhammad al-Hudhayni wrote to Imam Abu Muhammad (a.s.) saying, ‘My cousin has recommended a hajj to be performed on behalf of him with fifteen dinars every year, and this is not enough. What do you order me to do?’ The imam (a.s.) replied to him, ‘You make (the costs of) two (seasons of) hajj in one.

Allah is Aware of that.’[^163] Muhammad bin al-Hasan as-Saffar wrote to Imam Abu Muhammad al-Hasan bin Ali (a.s.), ‘Is the witness of the executer of a dead person accepted when he claims that the dead person has a debt on some one if there is another reliable witness?’ Imam Abu Muhammad (a.s.) replied, ‘If another reliable man witnesses with him, then the claimer has to take an oath.’ In replying to another letter like this, the imam (a.s.) said, ‘Yes, after taking an oath.’[^164] Muhammad bin al-Hasan as-Saffar wrote to Imam Abu Muhammad (a.s.) saying, ‘Some man made a will to his children, some of whom are adults and some are young children.
