(1) Sahih bi-ghayrihi (authentic due to corroborating evidence), and this chain is hasan (good). Husayn al-Mu'allim: he is Ibn Dhakwan.

For praying barefoot, there is a supporting witness from the hadith of 'Abdullah ibn al-Sa'ib, which preceded under number (648).
For praying wearing sandals, there is a supporting witness from the hadith of Abu Sa'id al-Khudri, which preceded before it.
