In The Name of Allaah, The Most Merciful, The Bestower of Mercy.
Imaam Ibnul Qayyim [rahimahullaah] said:
Hardship is only encountered by the one who abandons the Ma’loofaat and Awaa’id [i.e. those habitual things, deeds, practices, customs etc (Ref1)] for other than the sake of Allaah. As for the one who abandons them truthfully and sincerely from the bottom of his heart- for the sake of Allaah alone- then indeed he does not encounter any difficulty due to abandoning them except in the beginning, in order that he is tested as to whether he is truthful or untruthful in abandoning them? If he exercises a little bit of patience, its [i.e. that abandonment] will alternate into pleasure. Ibn Seereen said that he heard Shurayh swearing by Allaah that “A servant does not abandon anything for the sake of Allaah and finds a loss in that.”
And their statement [i.e. the people of knowledge] that ‘whoever abandons something for the Sake of Allaah, Allaah will replace it with what is better.” This is true. This compensation is of different types and the best of that which a person is compensated with is: the desire and yearning to get close to Allaah, seeking after Allaah’s pleasure, love of Allaah, and the heart granted-by way of it- tranquillity, strength, enthusiasm, happiness and being pleased with its Lord [The Most High].
