Man Lā Yaḥḍuruh al-Faqīh|Volume 2|Book 3|Chapter 2
وَ رَوَى مُحَمَّدُ بْنُ مُسْلِمٍ عَنْ أَحَدِهِمَا عَلَيْهِمَا اَلسَّلاَمُ قَالَ: قُلْتُ لَهُ اَلْمُحْرِمُ يَنْزِعُ اَلْحَشِيشَ مِنْ غَيْرِ اَلْحَرَمِ فَقَالَ «نَعَمْ» قُلْتُ فَمِنَ اَلْحَرَمِ قَالَ «لاَ».
It has been narrated from Muhammad ibn Muslim, from one of the Imams عليه السلام, who said: I asked him: "Can a person in the state of ihram remove grass from outside the Haram?" Imam عليه السلام replied: "Yes." I then asked: "What about from within the Haram?" Imam عليه السلام replied: "No."
