Abu Hurairah (may Allah be pleased with him) reports that the Messenger of Allah (peace and blessings of Allah be upon him) forbade anyone from putting on shoes while standing. 1 Imam Tirmidhi says:
1- This hadith is gharib (strange/rare).
2- Ubaidullah bin Umar Waraqee narrated this hadith from Mu’ammar, Mu’ammar from Qatadah, and Qatadah from Anas; both these ahadith are not considered authentic by the scholars of hadith. The memory of Harith bin Nubhan is not considered strong by the scholars of hadith.
3- We do not know of any original source for the hadith of Qatadah narrated from Anas.
