32. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from Ibrahim ibn Mahziyar who has said the following: “I once asked him (the Imam) عليه السلام, about a Jurmuq (a larger slipper worn over another one) if it is permissible to perform Salah (prayer) with it and I showed it to him (the Imam) and he (the Imam) said, ‘It is permissible to perform Salah (prayer) with it.’”
