From him, from Ahmad ibn Muhammad, from his father, from Ibn Abi Umayr, from Hammad, from al-Halabi, who said: I asked Imam al-Sadiq عليه السلام about covered mosques, is it disliked to stand in them? Imam عليه السلام said: “Yes, but prayer in them does not harm you today. And if justice were to be established, you would see for yourselves what would be done in that regard.” He (al-Halabi) said: “And I asked Imam عليه السلام, ‘May a man hang up his weapon in the mosque?’” Imam عليه السلام said: “Yes, but not in the ‘Great Mosque’ (al-Masjid al-Akbar), for my grandfather (Imam Ali ibn Husayn عليه السلام), peace be upon him, forbade a man from sharpening an arrowhead (mishqas) in the mosque.”
