Kohl ("Ithmad" or"Ithmid"), is a lead free ancient remedy. According to Islamic texts, pure "Ithmad" strengthens the nerves of the eye, and acts as a "cure all" for ocular diseases. It is highly recommended for the elderly whose eyesight has weakened. In this case, it is better to mix the Kohl with Musk.
It dissolves excess flesh around ulcers and closes the wounds while cleansing the areas around them. It relieves headaches when blended with pure, watery honey, prevents the blistering of burns, helps cure skin damages caused by fire and it nourishes the eyelashes making them grow nice and long.
Kohl is beneficial for the eye before going to sleep, especially since the eyes will not be moving thus the kohl will have the most favorable effect.
Here’s the sunna way of putting kohl on ur eyes
To apply Surma, Kohl (collyrium) to the eyes is Mustahab (peferable). Besides the benefit to the eyes, one would also get recompense (Thawab) for following the prophetic practice:
1.It is reported from Ibn Abbas (Ra) that the Prophet (SAW) used to apply the collyriyum of Ithmid (a mineral product) thrice to each eye every night before retiring to bed."
2.Hafiz Ibn Hajar and Mulla Ali Qari have preferred those traditions which indicate that the kohl-rod was applied to each eyes thrice.
3.Jabir (Ra) reports that the Prophet (SAW) has advised to apply the collyrium of Ithmid to the eyes as it increases the light of the eyes and helps grow the eye-lashes." (Shamaa'il)
There is no fixed time in applying Kohl( Surma) in general two to three times each eye (or three times in the right eye and twice in the left one) but applying it before retiring to bed is beneficial. (Ahsanul Fataawa Vol. 9 Pg. 74)
