3a] Should the Muslim pay attention to people’s tastes andcustoms and let his garment hang below his ankles? Is thereany isbaal involved in wearing pants?

3a]
“Were it not that your people have only recently left Jaahiliyyah behind, I would have demolished the Ka’bah andgiven it two doors.” In this case he left what was better for the sake of harmony and softening hearts.
Majmoo’ al-Fataawa (26/91)
Thirdly:
With regard to letting garments come below the ankles (isbaal) in general, and with regard to pants in particular, several points should be noted:
1 – Letting garments touch the ankles is a major sin. The prohibition on isbaal is not only due to arrogance; rather it is haraam in and of itself, and it is itself a kind of arrogance. If arrogance of the heart is added to that, then the sin is greater.
Al-Haafiz Ibn Hajar (may Allaah have mercy on him) said:
Ibn al-‘Arabi (may Allaah have mercy on him) said: It is not permissible for a man to let his garment go past his ankle and say “I am not letting it drag out of pride,” because the prohibition refers to it by name. It is not permissible if a thing is prohibited by name to say “I will not comply with it because the reason does not apply to me.” This is an unacceptable claim, rather his letting his garment drag is indicative of hisarrogance. End quote.
To sum up: Isbaal implies letting the garment drag, and dragging the garment implies showing off, even if the wearer did not intend to show off. This is supported by the report narrated by Ahmad ibn Munay’ via another isnaad from Ibn ‘Umar in a hadeeth which he attributed to the Prophet (peace and blessings of Allaah be upon him): “Beware of letting your izaar (lower garment) drag, for letting the garment drag is showing off.”
Fath al-Baari (10/264).
Shaykh ‘Abd al-‘Azeez ibn Baaz (may Allaah have mercy on him)said:
“Beware of letting your izaar (lower garment) drag, for lettingthe garment drag is showing off.” So all isbaal is regarded as showing off, because in most cases it is nothing else. Whoeverdoes not let his lower garment drag in order to show off, his action is a means that leads to that, and means come under thesame rulings as the ends.
Majmoo’ Fataawa al-Shaykh Ibn Baaz (6/383).
See also the answer to question no. 762 which explains the evidence for isbaal being haraam.
2 – It is not permissible for anyone to divide the religion into essential and trivial matters and those who divide it in this manner regard letting the garment hang below the ankles and shaving the beard as trivial matters. This is wrong, and the cause of it is ignorance of the rulings of Islam. These two actions are major sins. Look at how those who hold this view take the matter of committing major sins lightly because of this view.
See the response to them in the answer to question no. 12808 .
3 – Isbaal is not just the issue of the thawb, rather it also applies to the izaar (waist wrapper or lower garment), pants, shalwar and abayahs, and any other garment that the Muslim may wear.
4 – We should point out that that which is worn to mid-calf isthe izaar. The thawb and pants are not worn in this manner, rather they are worn above the ankle and it is not permissible for them to touch the ankle.
We have discussed these two issues (4 and 5) in the answer toquestion no. 10534 .
5 –It is not permissible to wear pants if they are tight and showthe shape of the ‘awrah.
See question no. 69789
And finally:
6 – Letting the pants come below the ankle is a major sin. Based on that, no attention should be paid to people’s taste and opinion about shortening them in accordance with the Sunnah of the Prophet (peace and blessings of Allaah be upon him), as we stated at the beginning of this answer. In factwe are surprised by the one who regards this shortening as spoiling the appearance of the Muslims but he does not regard the shortening of women’s clothes to mid-thigh in the same way, and he does not regard therepulsively tight pants worn by some young men in the same way, or the low-slung pants thatsome young people wear, or thehaircuts of young people which resemble animals such as lions, roosters, ducks and mice.
The brother who adheres to shortening his garments should not go to extremes in that. The ruling is that letting the garmentcome below the ankles is haraam, and there is no room for paying attention to people’s views on this matter. As for going to extremes in shorteningthem, there is room for manoeuvre. The brothers who adhere to this ruling should not expose themselves to mockery or focus this issue with people at the expense of other issues, and they should not create barriers between themselves and the people by going to extremes on such issues where sharee’ah has given room for manoeuvre./ - - - :-> Transtors: 1.http://free-translation.imtranslator.net/lowres.asp 2.http://translate.google.com/m?twu=1&hl=en&vi=m&sl=auto&tl=en
