Ash-Shaykh Abdul-Muhsin al-Abbad was asked the following question:
السؤال: هل السراويل المذكورة في الأحاديث التي مرت بنا هي ما نسميه اليوم بالبنطلون، أو بينهما فرق؟
Question: “Is the word ‘trousers’ that is mentioned in some of the hadeeths which has passed us (in the book) from what we call nowadays (known) as ‘pants’, or is there a difference between the two? ”
البنطلون هو من جنس السراويل، إلا أنّه ضيق يحجم الجسم، ويظهر الأجزاء ويبرزها.
“Pants is a type of trousers that is tight, it shows the shape of the body, and makes certain parts of the body apparent and manifest”
والسراويل -كما هو معروف فيها- أنها واسعة، ولا يصل الأمر فيها إلى أن تظهر أجزاء الجسم مثلما تظهر في البنطلونات الحديثة.
“And trousers as it is well-known regarding it, is that they are wide, and it doesn’t reach to an extent that certain parts of the body become apparent similar to how they become apparent in the modern-day pants”
A Side Note: What is intended by the word ‘wide trousers’ as Ash-Shaykh Albany mentioned are those trousers which do not become tight when going to ruko’ and sujood. However due it having an extra size to its width (i.e. being baggy), it remains wide even if the person were to go into ruko’ or sujood.
Ash-Shaykh Albaani, may Allaah have mercy upon him, said:
“(As) for Wearing pantaloon (i.e. tight pants), then we have spoken about it numerously. It is a foreign type of clothing. It is not permissible for a Muslim to wear it … (rather), wearing it in the prayer is more
deserving to be rebuked due to it showing the shape of the major awrah and the minor awrah. It shows the shape of the private parts and it
shows the shape of the thighs. In reality, those who are afflicted with the clothing pantaloon (i.e. tight pants) should bring to attention to themselves that it is appropriate they be like the women (by praying in the last rows of the congregation prayer), The best of the rows of the women is the last of it.”
The Reference: al Haawee min Fatawaa As Shaykh Albaani , page:335, print:
A Suggestion: If a person has to wear a certain uniform for work or school which are really tight, then what can be suggested is getting the same material for the pants tailored to become baggy or to purchase an extra size that is wider in its width. And Allah knows best.
Shaykh Saalih al-Fawzaan, may Allaah preserve him, said:
“It is not permissible to wear tight clothes which show the limbs and
the shape of a woman’s body. Tight clothes are not permissible for men
or women, but it is especially forbidden for women, because the fitnah in their case is greater.”
Al-Muntaqa min Fataawa al-Shaykh Saalih al-Fawzaan, 3/454
Also another suggestion for those coming from work or school to the masjid for jumah or for classes and so forth is that he brings along with him one piece of thawb in his bag or car to wear, being that Allah, The Most High said:
يَا بَنِي آدَمَ خُذُوا زِينَتَكُمْ عِندَ كُلِّ مَسْجِدٍ
“O Children of Adam! Take your adornment (by wearing beautiful Islamic clothes that are clean) for each prayer”
