Yep... Aqribat is-Saa'ataun wan shaqq al-Qamar: Again figurative and used a warning to established norms. Similar to Iza as-Shamsu kuwwirat. Do consider that Byzantium and Pars used the Moon and the Sun on their flags as a symbol.
Splitting of the Moon was also a physical act. Witnessed by many. At this time it becomes a matter of faith, hypnotix.
Even in those days Prophet (SAW) did not like it when people asked for proof in the way of miracles.
54.001 * Iqtarabati alssaAAatu wainshaqqa alqamaru
* The Hour (of Judgment) is nigh, and the moon is cleft asunder. **
54.002 *Wain yaraw ayatan yuAAridoo wayaqooloo sihrun mustamirrun
**But if they see a Sign, they turn away, and say, "This is (but) transient magic." *
So matters of faith - are not to be questioned and not always refered to as symbolic or just plain magic.
There were witnesses to the splitting of the moon BTW. And those witnesses were not Muslim. So they rejected it calling it magic.
Coming back to the Isra wal maraaj. That was also a physical journey because if you deny the physicality of it and try to justify it according to what our little brains can comprehend then we are showing lack of faith and the transcendance of Allah.
WE cannot even comprehend the simple fact that he has existed for ever and will exist for forever. So Isra Wal maaraaj is not something that should be discussed under the microscope either. We as ordinary humans will never understand.
