as-salaamu 'alaikum wa rahmatullaahi wa barakaatuh,
In this short but great article on Sahab.net, Shaykh 'Abdur-Razzaaq ibn 'Abdul-Muhsin al-Badr (may Allah preserve them both), mentions some of the Aayaat (Signs) of Allaah on the Earth. It's a good read that would in shaa' Allaah help one ponder more on the verses of the Qur'aan that talk about the Earth.
Among the things the Shaykh points out is the fact that Allaah has made mountains as pegs for the Earth so that the earth does not quake & shake from beneath our feet. Then he mentions what happens sometimes of Earthquakes in some parts of the worlds which causes destruction of lives and property and perhaps tens of thousands of people would perish in a single moment!
May Allaah help us ponder & reflect upon His signs, realize His right to be singled out with all worship and thank Him in speech and action.
