3. Ali ibn Ibrahim has narrated from his father from ibn abu ‘ Umayr from Jamil ibn Darraj who has said the following
“I once asked abu ‘Abd Allah (a.s.), about a man who suffers from an illness. In what condition he is allowed to perform Salah (prayer) in a sitting position? He (the Imam) said, ‘A man is unwell and experiences anguish; however, he knows better about himself. When he is able he must stand up.’”
