Hadith record

2. Ali ibn Ibrahim has narrated from his father from Ibn Abi ‘Umayr from ‘Umar ibn ‘Udhaynah who has said the following: “I once wrote to abu ‘Abd Allah (a.s.), asking about the limit of illness because of which one has permission to stop fasting and not to perform Salat (prayer) in a standing position. He (the Imam) said, ‘In fact, man is well aware of his soul,’ it is up to him to decide; he knows about his soul.’”
