Unlike most other types of Kohl, ithmid kohl carries immense health benefits for the eyes. Moreover, it is capable of making the white part of your eye (iris) more whiter and clearer whilst at the same time helping the natural growth of your eyelashes. It also makes your eyes appear bigger as a result of the kohl promoting healthy and stronger eyes.
In a hadeeth – classed as saheeh by Al-Albaani – the Prophet Sly llh lyh wslm is reported to have said that the best type of Kohl to use is that which is made of antimony. This clearly demonstrates the great benefits of ithmid Kohl as well as the significant importance that he attached to it.
Furthermore, the Prophet (sallallaahu alayhi wa sallam) himself used to apply ithmid Kohl to his eyes when going to sleep as a means of maintaining and improving his eyesight. This is a very important sunnah that should not be overlooked.
The kohl that is best used is the ithmid type which is reddish black in colour and obtained from Eastern countries. It is recommended that you apply it to your eyes three times every night before sleeping as this is the best way to maximise the benefits of it. It is also recommended that you start applying the kohl on your right eye and then move to the left, as this is what the Prophet (sallallahu alayhi wa sallam) did and it is what his companions used to do.
