Pondering the creation of the heavens and the earth and all that is between them, and contemplating the amazing variety of creation and the creation of man himself invigorates faith. This is because the sheer immensity of this creation points to the greatness of the Creator and His omnipotence. The consonance and harmony points to the vastness of Allāh’s knowledge and His all-encompassing wisdom. The innumerable blessings and abounding bounties it contains point to the vastness of Allāh’s mercy, His generosity and kindness. All of these factors lead a person to exalt its Creator, thank Him, remember Him and make the religion sincerely for Him alone. This is the essence and very spirit of faith.
Not for a blink of an eye is any object of creation free of His favours and pondering those leads one to have faith. This is why Allāh called the Messenger and the believers to give thanks to Him, “You who have faith! Eat of the good things We have provided for you and give thanks to Allāh if you worship Him alone.” (Q2:172)
Faith encourages a person to thank Allāh and giving thanks to Allāh revitalises and increases faith; both go hand-in-hand.
Dhikr of Allāh
Making the dhikr of Allāh and supplication which is the essence of worship increases faith. The remembrance of Allāh plants the tree of faith in the heart of the servant, it nourishes it and causes it to flourish. The more the servant makes the dhikr of Allāh, the stronger his faith becomes. Whoever loves Allāh would frequently make mention of Him. Loving Allāh is part of faith, indeed its very essence.
