Quran

Scholars said: A soul will not benefit from its faith when the Sun rises from the West because fear will be overwhelming so that all of its desires will subside and all of its strengths will diminish. All people will be certain of the end of this life, and therefore, they become like one who is facing his own death and tries to repent, but it will be too late. Al-Qurtubi: 9/130.
Question: A soul will not benefit from its faith when the Sun rises from the West. Why?

The wisdom behind that is obvious. Faith is only of benefit if it is faith in the unseen and is voluntary on the part of the individual. Once the signs appear, then it becomes a matter of faith in the seen and so faith will no longer be of benefit because it is more akin to faith when one has no other choice, like the faith of one who is drowning or burning to death and the like, who when they see death, give up what they were doing. Al-Saadi: 281.
Question: In the light of this verse, describe, in brief, the importance of believing in the unseen?

Man may attain good by means of his faith; acts of obedience, righteousness and piety are only of benefit and can only develop if the individual has faith. If his heart is devoid of faith, then, none of these deeds will be of any benefit to him. Al-Saadi: 282.
Question: Some disbelievers may do some good deeds in this life. Does that benefit them in the Hereafter? Why?

(Those who have made divisions in their religion and turned into sects) Mujahid said: "Those are the people of religious innovations and doubts in their minds." Ibn Taimyah: 3/117.
Question: Are the people of religious innovations included in this verse?

The correct religion is a general term; then Allah singles out for mention the noblest acts of worship, as He says, (Say, "Indeed, my prayer, my rites of sacrifice) - this is because of the virtue of these two acts of worship and what they imply of loving Allah, devoting worship sincerely to Him alone and drawing closer to Him in one's heart and by means of one's words and actions. Sacrifice means giving up what one loves of wealth or property for what is dearer to him, namely Allah. Al-Saadi: 282.
Question: Prayer and sacrifice are included in the first verse. Why are they singled out for mention?

Meaning: My life and my death (are for Allah): He gives me life and He takes it away. It also said that my life is spent in doing good deeds for Allah, and when my death comes I will die as a believer in Allah, the Lord of the worlds. Al-Baghawi: 2/86.
Question: How can living and dying be for Allah, Lord of the worlds?

This is both exhortation and intimidation, by reminding the believers that Allah is Swift in reckoning and punishment with those who disobey Him and defy His Messengers, and He is All-Forgiving, Most Merciful for those who take Him as protector and follow His Messengers in the narrations and commandments they conveyed. Sometimes, Allah calls His servants to them with exhortation, describing Paradise and making them eager for what He has for them. Other times, He calls them with intimidation, mentioning Hellfire and its torment and punishment, as well as, the Day of Resurrection and its horrors. At times, Allah mentions both. Ibn Kathir: 2/191.
Question: Calling others to Allah can be by exhortation or intimidation or both. Why?
