I heard Jabir bin ‘Abdullah saying, “A man passed through the mosque carrying arrows. Allah’s Apostle said to him, ‘Hold them by their heads.’ “
Narrated Abu Burda bin ‘Abdulla:
(on the authority of his father) The Prophet said, “Whoever passes through our mosques or markets with arrows should hold them by their heads lest he should injure a Muslim.”
Ruling: shouldn’t carry loaded/open-headed weapons inside a mosque because that puts Muslims in danger.
Islam teaches this. If Muslims do otherwise, can’t blame Islam for that, right?
Know what a ‘sutrah‘ is.
“I saw Ibn ‘Umar praying while taking his camel as a Sutrah in front of him and he said, “I saw the Prophet doing the same.”
This can be applied to other vehicles/means of transport as well.
