Is the intense feeling of certainty when thinking good of Allah, especially in matters such as the health of a marital relationship or the answering of prayers, considered delving into the knowledge of the unseen, and is there a fear that one might abandon their faith thereby? What is the ruling on this feeling, and how can it be avoided or dealt with if it is unlawful?

Having a good opinion of Allah Almighty and being certain that He will answer prayers is praiseworthy, as Allah Almighty says in the Hadith (definition) Qudsi: "I am as My servant thinks of Me," and as the Prophet, peace and blessings be upon him, said: "Supplicate to Allah while you are certain of being answered." Repelling the whisper of claiming knowledge of the unseen is achieved by busying oneself with the remembrance of Allah, making supplications, turning to what benefits one in their religion and worldly life, and by seeking forgiveness.
