Whoever passes through any of our mosques or markets with arrows with him, he should hold them by their heads lest he injures any of the Muslims with them
Authentic hadithعن أبي موسى الأشعري رضي الله عنه قال: قال رسول اللَّه -صَلّى اللهُ عَلَيْهِ وسَلَّم-: «من مرَّ في شيء من مساجدنا، أو أسواقنا، ومعه نَبْلٌ فَلْيُمْسِكْ، أو لِيَقْبِضْ على نِصَالِهَا بكفِّه؛ أنْ يصيب أحدا من المسلمين منها بشيء».
Abu Mūsa al-Ash‘ari (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "Whoever passes through any of our mosques or markets with arrows with him, he should hold them by their heads (blades) lest he injures any of the Muslims with them."
Explanation
Whoever passes through mosques, markets, and places where Muslims gather while he has a weapon with him, such as arrows or the like, he should hold it by its head well, in a firm grip, lest it injures any of the Muslims.
