Taking Shower or Bath

16. Ali has narrated from Ahmad ibn Muhammad from Muhammad ibn Aslam al-Jabaliy from Ali ibn abu Hamzah from Aban ibn Taghlib who has said the following: “I once said to abu ‘Abd Allah عليه السلام, ‘Sometimes when on a journey we do not find bran; if we can rub with flour.’ He (the Imam) said, ‘It is not harmful. It is bad only when belongings are destroyed and the body is harmed. If body is benefited then it is not bad. I sometimes command my slave to prepare bleached flour with oil and I rub with it.’”
