Benefits and Issues:

➊
Mu‘aṣfar means something dyed with ‘usfur.
It is a yellow substance with which clothes are dyed. (Muhammad Fuad Abdul Baqi, referencing al-Munjid)
However, he (al-Mufaddam) has explained it as:
Extremely red.
That is, it is so intensely red that it cannot be any redder.
It is possible that although the safflower (kasam) plant is yellow, the cloth dyed with it becomes red.

➋
From the word “dark,” it is understood that if the cloth dyed with safflower (kasam) is of a light color, then it is permissible for men.

(1) For details regarding coarse garments and silk cushions, see ahadith: 5168, 5169.

(2) “Thick, fine, and common silk”—in Arabic, the words istabraq, dibaj, and harir have been used. These are all types of silk. The details have already been mentioned in ahadith 5301, 5302. The purpose is that the use of every type of silk has been prohibited, but this prohibition is for men. However, the prohibition regarding silver utensils and silk cushions applies to both men and women, because these are items of common use.
