Is the carrying of weapons during the prayer of fear obligatory?
General Chapter
Al-Mughni
Book of the Prayer of Fear
Primary text
The carrying of weapons during the prayer of fear is held to be obligatory by Dawud and the second position of Al-Shafi'i. The evidence supporting obligation is the apparent meaning of the command, which indicates obligation. This is further supported by the phrase indicating exemption: "There is no blame upon you if there is injury to you from rain or you are sick that you lay down your arms" (Quran 4:102). The conditionality of removing blame based on harm indicates that carrying arms is required in the absence of such harm.
Supporting text
If there is harm from rain or sickness, laying down arms is permissible without disagreement, as the text explicitly removes blame in such circumstances.
