Please provide evidence for the bold, underlined statement, and by evidence I do not mean quotes from the quran.
And the Qur'an says in Surah Ambiya, Ch. No 21, Verse No. 31, in Surah Luqman, Ch. No. 31 Verse No.10, as well as in Surah Nahl, Ch. No. 16, Verse No. 15, that...'We have made the mountains standing firm on the Earth, lest it would shake with them and with you.' The function of the mountain in the Qur'an, is given to prevent the Earth from shaking. Nowhere does the Qur'an say that the mountain prevents the earthquake. The Arabic word for 'earthquake' is zilzaal or zalzala. But the words are Tamida which means to shake, swing, sway. Indicating, if the mountains were not there, if you would have walked, if you would have moved, even the earth would have moved with you - If you would have swayed, even the earth would have swayed with you. And we know normally when we walk on the Earth, the Earth does not shake.
It is all ignorance because you do not read and comprehend a scripture properly.
