How will he who died on Mars be resurrected, and what is its legal proof from the Qur’an and Sunnah? And does it rain on all planets and are there bacteria on Mars?

The prohibition against excessive questioning about things that are of no benefit has been mentioned, especially concerning matters for which no textual evidence has been revealed. This is because such revelations might displease the questioner or lead them into doubt and confusion. The verse, "O you who have believed, do not ask about things which if they are shown to you would distress you," has been used as evidence for the dislike of questions that serve no purpose. However, asking with the aim of learning and dispelling ignorance is permissible. The Prophet (peace be upon him) disliked excessive questioning and squandering wealth. Deep delving into differences that have no legal consequence, excessive elaboration on rare hypothetical cases, and questioning about unseen matters that the Sharia (definition) commands belief in without delving into their specifics, such as asking about the time of the Hour, are all blameworthy. A Muslim should busy himself with acts of obedience and learning religious knowledge, and believe in Allah's power to resurrect the dead without undue exertion or inquiry into the how.
