Hadith 8:1717
Abu Bakr narrated to us, he said: Hatim ibn Isma'il narrated to us, from Ja'far, from his father, from Ali, he said: When a man enters into Ihram and he is wearing a shirt, he should not remove it from over his head. He should tear it, then exit from it.
حدثنا أبو بكر قال حدثنا حاتم بن إسماعيل عن جعفر عن أبيه عن علي قال إذا أحرم الرجل وعليه قميص فلا ينزعه من رأسه يشقه ثم يخرج منه
