Remembering Allah should be done with both the tongue and the heart. However, being grateful to Allah is done out of love and repentance from the heart, and out of praise and glorification from the tongue, and out of obedience and servitude from the body.
—  [Ibn al-Qayyim, Al-Fawaa'id p.210]

This Ramadaan, Learn To Be Grateful.

The greatest ones who gave thanks to their Lord until they deserved to be described as shaakir and shakoor (thankful) are the Prophets and Messengers (blessings and peace of Allah be upon him).
As a believer we should all learn to be grateful and remember the many blessings we are being given by Allah.

Ibn Abi’d-Dunya mentioned that Dawud (peace be upon him) asked Allah, “What is the least of Your blessings?” Allah revealed to him, “O Dawud, take a breath.” Dawud did so, and Allah told him, “This is the least of My blessings on you.”
–Patience and Gratitude by Ibn Qayyim al Jawziyyah

So remember Me; I will remember you. And be grateful to Me and do not deny Me.
(Qur’an, Surah Al-Baqarah, 2:152)

Narrated Abu Bakrah:
When anything came to the Prophet (sallallahu alaihi wa sallam) which caused pleasure (or, by which he was made glad), he prostrated himself in gratitude to Allah.
