As that is all the Quran states about such a great miracle it appears even your God wasn't that impressed.<quoted text>
There are also different narrations for that particular incident, However, its also mentioned in the Quran
"The Hour has come near, and the moon has split [in two]. " 54:1
Surat Al Qamar (the moon)
The source of this story isn't even a hadith but a text of unknown origin that's supposed to be in the British library.interpretation by Asab al Nuzul
(The hour drew nigh and the moon was rent in twain)[54:1]. Abu Hakim Aqil ibn Muhammad al-Jurjani informed us (through verbal authorisation)> Abul-Faraj al-Qadi> Muhammad ibn Jarir> al-Husayn ibn Abi Yahya al-Maqdisi> Yahya ibn Hammad> Abu Awanah> al-Mughirah> Abul-Duha> Masruq> Abd Allah who said:The moon was split at the time of the Messenger of Allah, Allah bless him and give him peace, so the Quraysh said:This is an act of sorcery from the son of Abu Kabshah; he has cast a spell on you. Ask, therefore, the travellers whether they saw the moon split. They asked some travellers and they confirmed it. Allah, exalted is He, then revealed (The hour drew nigh and the moon was rent in twain. And if they behold a portent they turn away and say: Prolonged illusion)[54:1-2].
From your own link:this was one of Mohammed's miracles during his prophecy, such miracles are intangible, anyways the "Moon Splitting Miracle" was witnessed by an Indian King
The established historical sources from Kerala suggest that Cheraman Perumal lived in the ninth century. That's 3 centuries too late.
Personally I don't trust any story coming out of India.
