I think that sometime, somewhere I heard that Muslims should avoid asking so many details about faith and going deep in analyzing haram and halal. Arguments for this is mentioned in Surat al-Baqarah verse 67-71 (the verses which tells the story of slaughtering a cow) :
67 And (remember) when Musa (Moses) said to his people: "Verily, Allah commands you that you slaughter a cow." They said, "Do you make fun of us?" He said, "I take Allah's Refuge from being among Al-Jahilun (the ignorant or the foolish)."
68 They said, "Call upon your Lord for us that He may make plain to us what it is!" He said, "He says, 'Verily, it is a cow neither too old nor too young, but (it is) between the two conditions', so do what you are commanded."
69 They said, "Call upon your Lord for us to make plain to us its colour." He said, "He says, 'It is a yellow cow, bright in its colour, pleasing to the beholders.' "
70 They said, "Call upon your Lord for us to make plain to us what it is. Verily, to us all cows are alike. And surely, if Allah wills, we will be guided."
71 He [Musa (Moses)] said, "He says, 'It is a cow neither trained to till the soil nor water the fields, sound, having no other colour except bright yellow.' " They said, "Now you have brought the truth." So they slaughtered it though they were near to not doing it.
Another arguments for avoid going in details and too much analyzing so deep is this hadith:
"Haram is clear, Halal is clear other thinks is Allah's mercy"
I really do not know if this is the right argument, and does this hadith exist at all? So, I will love to hear the opinions of those who know more than me. Also, if this is the right view it could be the answer to many questions asked here.
