Does Allah love handicrafts, manufacturing, and scientific experiments that are pursued for recreation and benefit? And is a person rewarded for them and admitted into Paradise thereby?

Inventions, innovations, and sciences that benefit Islam and Muslims and are needed by them are desirable, and their initiator will be rewarded for them if he seeks the reward from Allah. As for those that are harmful to Islam and Muslims or include শরয়ী (Shar'i) prohibitions, they are forbidden. And whatever is neither beneficial nor harmful, such as entertainment inventions that do not involve a Shar'i transgression, is permissible.
