Allah said,

﴿وَإِذَا حَلَلْتُمْ فَاصْطَـدُواْ﴾

(But when you finish the Ihram, then hunt,) When you end your Ihram, it is permitted for you to hunt game, which was prohibited for you during Ihram. Although this Ayah contains a command that takes effect after the end of a state of prohibition (during Ihram in this case), the Ayah, in fact, brings back the ruling that was previously in effect. If the previous ruling was an obligation, the new command will uphold that obligation, and such is the case with recommended and permissible matters. There are many Ayat that deny that the ruling in such cases is always an obligation. Such is also the case against those who say that it is always merely allowed. What we mentioned here is the correct opinion that employs the available evidence, and Allah knows best.
