Using a computational method based on an allegedly implicit meaning of certain Qur'anic verses

Q: Is it permissible to know and predetermine the beginning of the blessed Month of Ramadan by the means of calculation based on the implicit meaning of the noble Qur'anic verse number twenty-five of Surah Al-Kahf?

A: The Islamic correct method of determining the beginning of the Month of Ramadan can be applied by sighting the new moon of Ramadan or by the completion of the Month of Sha'ban as thirty days, following what has been authentically reported from the Prophet Muhammad (peace and blessings of Allah be upon him) who said: Observe the fast upon sighting the new moon (of Ramadan), and end the fast upon sighting the new moon (of Shawwal), and if the sky is overcast (and you cannot see it), complete the term of the month of Sha`ban as thirty days. As for using a computational method based on an allegedly implicit meaning of certain Qur'anic verse and their allusive numbers in order as a way to predetermine the beginning of the Month of Ramadan or any other lunar Months, this is an invalid method which keeps people away from the real understanding of the Holy Qur'an and from reflecting upon its true meanings. This is merely a waste of time and effort on useless things. Therefore, it is an obligation upon Muslims to eschew these fancies and to busy themselves with what is beneficial for their religion, lives, and Afterlife.
