Praying with dried Mazi

Question

If my clothes are soiled with mazi with an amount greater than a rupee coin (the hollow portion of palm), and if I pray with these clothes on without washing thrice, is my Salaah valid?

Answer 1

 In the case mentioned above, it is necessary to wash off the impurity (mazi); Salah will not be lawful without washing it: وعفا الشارع عن قدر درھم وان کرہ تحریما، فیجب غسلہ وما دونہ تنزیھا فیسن وفوقہ مبطل فیفرض (الدر المختار)
