Sa'd from Ahmad ibn Muhammad from al-Hasan ibn Mahbub from Ali ibn Ri’ab from Ziyad ibn Suwayqah: Abu Ja‘far عليه السلام, peace be upon him, said: “The Messenger of Allah سبحانه وتعالى, peace be upon him and his family, said: "There is no harm if one of you prays in a single garment with its buttons undone. Indeed, the religion of Muhammad صلى الله عليه وعلى آله وسلم, peace be upon him and his family, is upright and easy (hanif)."
