Dua is not only about asking Allah; it is also about the conversation with Allah!
Shaykh al-Islam Ibn Taymiyyah (رحمة الله عليه) said:
❝Sometimes, I have a certain need that only Allah can fulfil, so I call upon Him.
Then, I find that the door of dialogue with Allah opens up for me, and through it I taste the sweetness of discourse with Him and the joy of knowing Him that far surpasses the urgency of obtaining an answer to my prayer, and so I prefer for the answer to my prayer be delayed for fear of losing this connection once my need is fulfilled.❞
[Majmu al-Fatawa, 10/333].
