God creates everything with for a reason, for good. It would be a grave mistake to think about the past and then get sad. God has created the past auspiciously and it is already done. One would live the same destiny every single time even if he is sent to this world for a thousand times. People would not remember anything negative about their past in Heaven. Once a believer targets the good pleasure of God, he would not attach any importance to the past. A believer should put his trust in God and keep his heart at ease.

Some people do not believe in God. As for some of those who say that they believe in God, they may, without realizing it, draw close to associating partners with God through various thoughts and actions. This truth is revealed in the Qur'an as follows: “And most of them believe in God only when they can attribute partners (to Him).” (Surah Yusuf, 106) Associating partners with God is not limited merely to turning to idols, as most people think. Its real danger lies in failing to comprehend, as one ought, God's absolute power, sovereignty, and His uniqueness in creation. https://www.harunyahya.info/en/articles/associating-partners-with-god-is-a-disease-of-the-soul

Love is the reason of existence of the world. Love is what God loves the most. It is the purpose of existence. God creates the whole universe for love; because He loves love. And love is also what He wants to have among people. He wants Himself to be loved.

According to a widely held understanding in society, some people accept “divine will”—that is, Allah’s infinite will, yet attribute an independent power of choice to humans under the name of “partial will.” In other words, they believe in the existence of a model where people are capable of determining their own paths and holding the power to make decisions. Adopting this opinion as a fundamental belief, they say, “It is predetermined in your destiny that you will go from point A to point B, but how you get there is up to you,” or “Marrying this person is in your destiny, but how that marriage will proceed is up to you.” However such understanding is a serious misconception stemming from a failure to properly understand Allah’s power. Allah states in His verses that there is no decision-making authority other than Himself. This truth is clearly revealed in verses 30 of Surah Al-Insan and 29 of Surah At-Takwir, where it is stated, "You cannot will unless Allah, the Lord of the worlds, wills it." https://www.harunyahya.info/en/articles/Both-Absolute-will-and-particular-will-belong-to-Allah
