O you who have believed, do not ask about things which, if they are shown to you, will distress you. But if you ask about them while the Qur'an is being revealed, they will be shown to you. Allah has pardoned that which is past; and Allah is Forgiving and Forbearing.A people asked such [questions] before you; then they became thereby disbelievers. (Quran 5:101-102)
first of all SILVERTONGUE thanks for the wonderful article. but talking about the BANI ISRAEL think logically they are doing very well today and it feels great pain to see our brothers suffering around the world, but anyways its not something you and I can do about.
the lines of Quran that you have sent I have not verified but rely on your findings. Its an ayat mentioned maybe while the Quran was being revealed as it says "But if you ask about them while the Qur'an is being revealed, they will be shown to you". today Quran has been revealed so if doubts are there today I think one has no choice but to ask questions.
the questions asked on this forum are as it is not from the revelation of Quran or about Islam but its about our shia/dawoodi bohra community especially not what was revealed by Quran but what is said in the bayans.
coming to the other part of your answer about a man asking about Hajj , Prophet Mohammed not liking people asking questions or other things I suppose is from the write up by "Sayyid Abul Ala Maududi - Tafhim al-Qur'an". Can you ask him a question from where did he get these details.
one more thing this is the best answer to give to a logical mind that if you ask too many questions you will be destroyed. Truth actually should never be afraid of questions.
