It was narrated from Ibn ‘Umar that a man said: “Messenger of Allah ﷺ, what clothes should we wear when we enter Ihram?” He said: “Do not wear a Shirt (or shirts), or ‘Imamahs, or pants, or Khuffs - unless someone cannot find sandals, in which case he should cut them (the Khuffs) so that they come beneath the ankles — or any garment that has been touched by (dyed with) wars or saffron.” (Sahih)
