Splitting of the Moon, Ratan Baba is nothing but fiction and Mullah Qadri is good at spreading conjecture.
Surah 54. Al-Qamar – The Full Moon
[Author’s Note] This is the 54th Surah of the Qur’an. It has 55 verses. Historically, the strong opponents of the Prophet, the Quraish Tribe of Makkah, had full moon on their banner as the logo. This Surah predicts their defeat at the hands of a few ill-equipped believers, while recapping some history as a forewarning. God reiterates that He is always with His Messengers as they are with Him. Unjust system in any society heralds its demise.
With the Glorious Name of God, the Instant and Sustaining Source of all Mercy and Kindness
54:1 The Hour of Revolution is fast approaching. And the moon bearing banner is torn asunder.
[The use of the past participle here and at many other places in the Qur’an reflects the certainty of things to happen. As-Saa'ah = The Hour = The Last Hour = The Revolution = The decisive moment = Resurrection. Shaqqal Qamar is usually given the literal translation = The moon is split. Then there are fabricated Ahadith which go on to say that the exalted Prophet split the moon into two halves pointing a finger at it! Additional reports want us to believe that one half of the moon then came down, entered the collar of the Prophet and exited through his sleeve. Not only all this is contrary to the Qur’an and to reason, the whole story defeats its own validity. It fails to name a single person present there who was awestruck by this 'miracle' and embraced the Message as a result. The Qur’an is a Book consistent with itself and vehemently rejects any notions contrary to reason and to the changeless universal laws. Moreover, attainment of belief is a matter of choice. God does not will to compel or coerce anyone into believing. Stunning the human intellect by means of 'miracles' would counter this Divine Laws]
