(35) باب مَا جَاءَ فِي كَرَاهِيَةِ أَنْ يَنْتَعِلَ الرَّجُلُ وَهُوَ قَائِمٌ
Narrated Abu Hurairah:
"The Messenger of Allah (ﷺ) prohibited that a man should put on sandals while he is standing."[Abu 'Eisa said:] This Hadith is Hasan Gharib. 'Ubaidullah bin 'Amr Ar-Raqqi reported this Hadith from Ma'mar, from Qatadah, from Anas. Both of the Ahadith are not correct according to the people of Hadith. Al-Harith bin Nabhan is not a Hafiz according to them, and we do not know any basis for the narration of Qatadah from Anas.
