Sayyiduna Ibn Abbas (may Allah be pleased with them both) said: Our women used to apply dye after the ‘Isha prayer, and when morning came, they would untie it, perform ablution, and offer prayer. After performing the Zuhr prayer, they would tie it again, and when it was time for the ‘Asr prayer, they would untie it. This would give a better color, and they would not miss the prayer because of the dye (or henna).
