It is reported about Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that he saw a Bedouin praying with his lower garment hanging down, and he said: The one who lets his lower garment hang down during prayer is not in anything lawful or unlawful from Allah Almighty.
Al-Tabarani recorded it, and its narrators are thiqat (trustworthy).
