He who trails his lower garment out of pride
The Prophet (sal Allahu alaihi wa sallam) said, “On the Day of Resurrection, Allah will not look at him who trails his lower garment out of pride.”
[Sahih Al-Bukhari and Muslim]
We benefit from this Hadith that Allah not looking at an arrogant man means the restraint of the flow of His Grace towards him. Instead of Allah’s Mercy, His Wrath will smite the arrogant.
The garment which man wears to cover the lower half of his body is called Izar in Arabic. Hence pyjamas, trousers, Shalwar and Tahband will be taken as Izar.
The Messenger of Allah (sal Allahu alaihi wa sallam) has emphatically said that the Izar should remain above the ankle of men as its dragging down signifies arrogance.
Indeed it displays the attitude of the haughty whose grim fate can be seen in this Hadith.
And Allah knows best!
