"Do not use kohl unless it cannot be avoided. The Messenger of Allah entered upon me when Abu Salamah died and I had put some aloe juice on my eyes. He said: 'What is this, O Umm Salamah?' I said: 'It is aloe juice, O Messenger of Allah, there is no perfume in it.' He said: 'It makes the face look bright, so only use it at night, and do not comb your hair with perfume or henna, for it is a dye.' I said: 'With what can I comb it, O Messenger of Allah?' He said: 'With lote leaves -cover your head with them.'"
Sunan an-Nasa'i Book 27, Hadith 151
← Previous Hadith "It is not permissible for a woman who believes in Allah and the Last Day, to mourn for anyone who dies for more than three days, except for a husband; she should not use kohl, dye nor wear dyed clothes."

Sunan an-Nasa'i Book 27, Hadith 150 Next Hadith → "A woman from the Quraish came and said: 'O Messenger of Allah, my daughter's eyes are inflamed; shall I apply kohl to her?' (The daughter's) husband had died so (the Prophet) said: 'Not until four months and ten days (have passed).' Then she said: 'I fear for her sight.' He said: 'No, not until four months and ten days (have passed). During the Jahiliyyah one of you would mourn for her husband for a year, then when one year had passed she would throw a piece of dung.'"
