Ibn 'Abbaas Radiyallahu 'Anhu says:
"Rasulullah Sallallahu 'Alayhi Wasallam said: 'Use kuhl made of ithmid on the eye; it brightens the eyesight, and strengthens and increases the growth of the eye lashes'. (Sayyidina Ibn'Abbaas Radiyallahu'Anhu also used to say) 'Rasulullah Sallallahu 'Alayhi Wasallarn had a small container for keeping kuhl, from which he applied kuhl in each eye three times every night"'
Ibn 'Abbaas Radiyallahu 'Anhu reports:
"Rasulullah Sallallahu 'Alayhi Wasallam applied kuhl of ithmid three times in each eye before sleeping'. In a narration also from Ibn 'Abbaas Radiyallahu 'Anhu, it is reported: "Rasuluilah Sallallahu'Alayhi Wasallam had a small container for keeping kuhl, from which he applied in each eye kuhl three times before sleeping'.
Jaabir bin 'Abdullah Radiyallahu 'Anhu says:
"Rasulullah Sallallahu 'Alayhi Wasallam said: 'Use the kuhl made from ithmid for the eyes. It brightens the vision and strengthens the growth of the eye lashes'.
Ibn 'Abbaas Radiyallahu 'Anhu says:
"Rasulullah Sallallah 'Alayhi Wasallam has said: 'The best from among all the kuhl used by you is the one made from ithmid. It brightens the eyesight and strengthens the growth of the eye lashes"'
'Abdullah bin 'Umar Radiyallahu 'Anhu related the same hadith from Rasulullah Sallallahu 'Alayhi Wasallarn that:
"Verily use the kuhl made from ithmid. It brightens the vision and strengthens the growth of the eye lashes".
