Ibn Al-Qayyim explained the meaning of the first had?th saying: ‘This had?th indicates that letting garments down is a sin, and whoever commits a sin is ordered to perform wud?’ and Sal?t for doing Wud?’ extinguishes the fire of the sin [in one’s soul]’. (1)
The prophet ( - ) may have wanted the man to pay head to the reason that made the prophet ( - ) order him do Wud?’ although he was already pure, and consequently to realize the sin he has commited. And this blessing of the prophet’s ( - ) comited to do Wud?’ - as an indication of external purity - leads to the purity of one’s psyche of the stain of conceit, for external purity surely leads to internal purity. (2)
It is worth mentioning’that this ruling regarding Isb?l [letting Iz?r down] applies also on letting down the Sar?w?l and Qam?s’. (3)
A muslim, then, should pull up his clothes when ever they go down, and he will not be considered of those who let their Iz?r down intentionally.
Those who let their trails down intentionally to reach the ground, whether they by Bisht, Sar?w?l or Qam?s -they will surely fall in the circle of the threat mentioned in the a had?th for they have no excuse in doing such a prohibited act.
Accordingly, a muslim must be aware of letting his garment down and fear All?h ( - ) of such a prohibited act. His clothes must not exceed his heels in order to be of those who act in accordance

Refer to “Bathl Al-Majh?d” (vol. 4 / p. 296), “Dal?lul Falih?n” (vol. 2 / p. 283), “Ad-Dinul Kh?lis “(vol. 6 / p. 166) and “Al-Manhal Al-’Athb Al-Mawr?d “(vol. 5 / p. 123) Al-Q?r? added: ‘The prophet ( - ) ordered the man to re perform the Wud?’ as a sign of rejection for what he did of letting his Iz?r down since the man didn’t realize his mistake at first. And there is an indication that the Sal?t of him who lets his Iz?r down is not acceptable, but none of the reverend ‘Ulamah held this opinion because the had?th is weak!! Had this had?th been authentic, it is then abrogated for the great group of ‘Ulamah held opposite opinion’.
