Paradise will not be attained with wishful thinking….
فَمَن كَانَ يَرۡجُواْ لِقَآءَ رَبِّهِۦ فَلۡيَعۡمَلۡ عَمَلاً۬ صَـٰلِحً۬ا وَلَا يُشۡرِكۡ بِعِبَادَةِ رَبِّهِۦۤ أَحَدَۢا
“So whoever hopes for the Meeting with his Lord, let him work righteousness and associate none as a partner in the worship of his Lord.”
[Soorah Al Kahf ayah 110]
Shaykh Saalih Al Fawzan حفظه الله said:
“This (ayah) is a proof that just hope (in meeting Allaah/attaining paradise) alone is not sufficient, it is a must that there is (righteous) action. As for you hoping in Allaah however do not accompany it with action then you have negated the reason (that will help you attain your meeting with Allaah).”
