6. Muhammad ibn Yahya has narrated from Muhammad ibn al-Husayn from Muhammad ibn ‘Abd Allah ibn Hilal from ‘Uqbah ibn Khalid who has said the following: “I once asked abu ‘Abd Allah عليه السلام, about a man who becomes ill in the month of Ramadan. When he becomes well he decides to perform Hajj. What is he required to do about Qada’ (compensatory fast) of the fast? He (the Imam) said, ‘When he comes back he must do its Qada’ (compensatory fast).’
