Save those who repent and amend and hold fast to Allah and make their religion pure for Allah (only). Those are with the believers. And Allah will bestow on the believers an immense reward.

Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
The Statement of Allah: "O you who believe! Make not unlawful the Tayyibãt (all that is good as regards foods, things, deeds, beliefs, persons) which Allah has made lawful to you..." (V.5:87)
Narrated `Abdullah:
We used to participate in the holy wars carried on by the Prophet (ﷺ) and we had no women (wives) with us. So we said (to the Prophet (ﷺ) ). "Shall we castrate ourselves?" But the Prophet (ﷺ) forbade us to do that and thenceforth he allowed us to marry a woman (temporarily) by giving her even a garment, and then he recited: "O you who believe! Do not make unlawful the good things which Allah has made lawful for you."
