The Book of the Prohibited actions
Undesirability of Wearing one Shoe or Sock
وَعَنْ جَابِرٍ رَضِيَ اللَّه عَنْهُ أَنَّ رَسُولَ اَللَّهِ صَلَّى اللَّه عَلَيْهِ وَسَلَّمَ نَهَى أَنْ يَنْتَعِلَ الرَّجُلُ قَائِمًا". ((رَوَاهُ أَبُو دَاوُد بإسناد حَسَن ))
Jabir (May Allah be pleased with him) said: The Messenger of Allah (ﷺ) forbade a person wearing (tying up) his shoe while standing. [Abu Dawud with a good Isnad].
