The first of the six fundamentals of îmân is to believe that Allâhu ta’âlâ exists. A person with reason and scientific knowledge can understand this easily by thinking. Allahu ta’âlâ in many places of Qur’ân al-kerîm, scolds and disgraces disbelievers because they didn’t use their minds; they didn’t think by observing the earth, the skies and themselves, and thus attain îmân. The book Ma’rifatnâme writes, “Sayyed Sharîf Jurjânî, a great Islamic scholar, says that the knowledge of astronomy helps a wise and reasonable person to realize the existence of Allahu ta’âlâ. Imâm-i Ghazâlî says that he who does not know astronomy and anatomy cannot realize Allah’s existence. ”

Hadrat Imâm-i Rabbânî says in the  67th letter of the second volume of his Maktûbât:

We have received your valuable letter, which you so kindly sent to us. Hamd and gratitude be to Allâhu ta’âlâ, because at such a time as this when doubts have been on the increase, you fortunate people, though you need nothing and though there is no occasion, have been taking notice of these faqîrs and thinking of us, who have been left, forgotten in the nook, thus showing that you have belief in this way, which befits your pure ancestry. It is such a great blessing that your various occupations and relations do not prevent you from this great fortune, nor do the confusing things you have to do hinder this love of yours. You should fulfil the thanks for this great blessing, and you should be hopeful, since it is stated in a hadîth-i-sherîf, “In the Hereafter everybody will be with the person whom he loves in the world!”
