How can a person love God when they feel that new tribulations distance them from Him, and that the unfulfillment of their desires might make them doubt God’s concern for them, thereby affecting their faith?

To answer your questions:

1. Difficulty in contemplating the truth: Belief in the Hereafter and the Resurrection is a fundamental pillar of faith, and doubt in it negates faith. One must seek refuge in Allah from whisperings and adhere to the proofs from the Qur’an and Sunnah.

2. Discontent with what Allah has decreed: A believer must be patient and content with what Allah has decreed for him in terms of destinies and provisions. Calamities expiate sins and bring a servant closer to Allah, along with patience and contentment.

3. Intensity of worries: Its cure is through supplication: "O Allah, I seek refuge in You from worry and grief, from incapacity and laziness, from stinginess and cowardice, from the burden of debt, and from being overpowered by men," and by frequently remembering Allah and sending blessings upon the Prophet.

4. The desired outcome from supplication not being achieved: There are three forms for the answering of supplication: giving the servant what he asked for, averting an impending calamity, or postponing its reward until the Day of Judgment, all of which are good.

5. We advise you not to indulge in whisperings that lead to doubt in the fundamentals of religion. You must repel them by seeking refuge in Allah, remembering Allah, or by reciting the Qur’an.
