What is the explanation of al-Ṣiddiq’s oath not to spend on Miṣṭaḥ?

Question:
Is it considered a sin to swear not to spend on him?

Answer:
What appears from this is that when he displayed the evil accusation and accused ‘A’ishah of what he accused her of, he became an open sinner, not worthy of being treated kindly. However, he could have been ordered to work and earn, as he was young. This is a matter of kindness, a matter of maintaining ties that are not obligatory for al-Ṣiddiq. First, Miṣṭaḥ is distant, and second, he is able to work and earn. There are other reasons as well. There is no evidence for the obligation of financial maintenance on al-Ṣiddiq; it is a matter of generosity and kindness. When he heard what he said, he cut it off from him. When the verse was revealed, he restored it to him. Not all maintaining of family ties is obligatory; some of it is obligatory, and some of it is recommended.
