Sayyiduna Umar bin al-Khattab saw dyed garments on Sayyiduna Talhah bin Ubaydullah (may Allah be pleased with them both) while he was in ihram, and said to him: O Talhah! What are these dyed garments? Sayyiduna Talhah (may Allah be pleased with him) said: O Commander of the Believers! It is only clay (red ochre) dye. Sayyiduna Umar (may Allah be pleased with him) said: O group! You are leaders whom the people follow. If an ignorant man were to see this garment, he would say: Talhah bin Ubaydullah used to wear dyed garments during ihram. So do not wear anything of these dyed garments.
