Shaykh Sālih al-Usaymi, [may Allāh preserve him] said:
“Fasting and [recitation of] the Qur’ān cleanses impurities of the hearts which are accumulated due to sicknesses [of the heart]: desires, lusts and doubts, in the same manner as water and soap cleanses [our] bodies and clothes. Therefore, sieze the opportunity and take advantage of their coming together in [the blessed month of] Ramadān, and take from them to become amongst those who are truly fortunate¹. In order to attain complete purification of your hearts, therefore [elevate and] purify yourself so that you may become successful.
Footnote:
¹ And none is granted it except the owner of the great portion (of happiness in the Hereafter i.e. Paradise and of a high moral character) in this world.
