English Translation of Hadith
Hazrat Abu Hurairah (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) said, "You will covet for getting a position of authority, but remember that it will be a cause of humiliation and remorse on the Day of Resurrection.”

Lesson : as mentioned above in Surah Al-Kahf Ayat 95."He said: "That (wealth, authority and power) in which my Lord had established me is better (than your tribute)".This Hadith urges people, particularly the incapable ones, to shed off the ambition to achieve rulership and power. It is feared that owing to their lack of talent they will mismanage the task which will be assigned to them. This will render them guilty with Allah. The Prophet [SAWW](PBUH) dissuades such people from accepting any government portfolio as in this way they will remain safe and trouble-free. Yet, if a deserving person gets a job of high responsibility, he should do his utmost to do full justice to it, so that he may be spared remorse on the Day of Resurrection.

[18].Surah Al-Kahf [The Cave]

English Translation of Al-Quran
[18].Surah Al-Kahf [The Cave]
Ayat 94. They said: "O Dhul-Qarnain! Verily! Ya’jûj and Ma’jûj (Gog and Magog) are doing great mischief in the land. Shall we then pay you a tribute in order that you might erect a barrier between us and them?"
Ayat 95. He said: "That (wealth, authority and power) in which my Lord had established me is better (than your tribute). So help me with strength (of men), I will erect between you and them a barrier.
[Tafseer] Who were the Gog and Magog people? This question is connected with the question, who was Dhu al Qarnain?. What we are mainly concerned with is the spiritual interpretation. The Conqueror had now arrived among a people who were different in speech and race from him, but not quite primitive, for they were skilled in the working of metals, and could furnish blocks (or bricks) of iron, melt metals with bellows or blowpipes, and prepare molten lead (18:96). Apparently they were a peaceable and industrious race, much subject to incursions from wild tribes who are called Gog and Magog. Against these tribes they were willing to purchase immunity by paying the Conqueror tribute in return for protection. The permanent protection they wanted was the closing of a mountain gap through which the incursions were made. Dhu al Qarnain was not greedy and did not want to impose a tribute to be carried away from an industrious population. He understood the power which Allah had given him, to involve duties and responsibilities on his part-the duty of protecting his subjects without imposing too heavy a taxation on them. He would provide the motive force and organizing skill. Would they obey him and provide the material and labour, so that they could close the gap with a strong barrier, probably with well-secured gates? The word radm, translated "Barrier," does not necessarily mean a wall, but radier suggests a blocked door or entrance.

English Translation of Hadith
Hazrat Abu Musa (May Allah be pleased with him) reported: The Messenger of Allah [SAWW](PBUH) said, "Allah, the Exalted, will continue to stretch out His Hand in the night so that the sinners of the day may repent, and continue to stretch His Hand in the daytime so that the sinners of the night may repent, until the sun rises from the west".

Lesson : as mentioned above in Surah Al-Furqan Ayat 70."those who repent and believe (in Islamic Monotheism), and do righteous deeds, for those, Allah will change their sins into good deeds, This Hadith confirms an essential Attribute of Allah, i.e., the Hand which He stretches out anytime He wishes without drawing similarity to it, nor interpretation. Such was the attitude of the pious predecessors with regards to all of the essential Attributes of Allah. It is deduced from this Hadith that if one commits a sin during any hour of day or night, he should immediately seek the forgiveness of Allah as a result.

Ayat 70. (They will abide therein in disgrace torment will be doubled to them), Except those who repent and believe (in Islamic Monotheism), and do righteous deeds, for those, Allah will change their sins into good deeds, and Allah is Oft-Forgiving, Most Merciful.
[Tafseer
of Ayat] 70. the Penalty on the Day of Judgment will be doubled to them, and they will dwell therein in ignominy, Unless he repents, believes, and works righteous deeds, for Allah will change the evil of such persons into good, and Allah is Oft-Forgiving, Most Merciful, But even in the case of great crimes, if there is true repentance as tested by a changed life in conduct, Allah’s Mercy is available, and it will transform the repentance’s nature from evil to good.

Ayat 66. Evil indeed it (Hell) is as an abode and as a place to dwell.
Ayat 67. And those, who, when they spend, are neither extravagant nor niggardly, but hold a medium (way) between those (extremes).
[Tafseer] of Ayat 66. "Evil indeed is it as an abode, and as a place to rest in"; The misery which results from sin is not only grievous to live in ("an abode") but also grievous "to rest in" or "to stand in", if it be only for a short time. [Tafseer] of Ayat 67. Those who, when they spend, are not extravagant and not niggardly, but hold a just (balance) between those (extremes); In ordinary spending, this is a wise rule. But even in charity, in which we give of our best, it is not expected that we should be extravagant, i.e., that we should either do it for show (to impress other people), or do it thoughtlessly, which would be the case if we "rob Peter to pay Paul". We should certainly not be miserly, but we should remember everyone’s rights, including our own, and strike a perfectly just balance between them.

English Translation of Hadith
Hazrat Anas (May Allah be pleased with him) reported: The supplication most often recited by The Messenger of Allah [SAWW](PBUH) was: "Allahumma atina fid-dunya hasanatan, wa fil-akhirati hasanatan, wa qina `adhab-annar (O our Rubb! give us in this world that which is good and in the Hereafter that which is good, and save us from the punishment of the Fire).”

Lesson : as mentioned above in Surah Al-Furqan Ayat 66. Evil indeed it (Hell) is as an abode and as a place to dwell" It is desirable to recite this Du`a which is mentioned in the Qur’an (2:201) and which comprehends all that is good both in this life and the Hereafter. The Messenger of Allah [SAWW](PBUH) made it a habit to recite this Du`a, and the Companions were eager to follow him in all his words and actions.

Ayat 68. And those who invoke not any other illah (god) along with Allah, nor kill such life as Allah has forbidden, except for just cause, nor commit illegal sexual intercourse and whoever does this shall receive the punishment.
Ayat 69. The torment will be doubled to him on the Day of Resurrection, and he will abide therein in disgrace;
[Tafseer
of Ayat] 68. Those who invoke not, with Allah, any other god, nor slay such life as Allah has made sacred except for just cause, nor commit fornication; – and any that does this (not only) meets punishment. Here three things are expressly condemned: (1) false worship, which is a crime against Allah; (2) the taking of life, which is a crime against our fellow creatures; and (3) fornication, which is a crime against our self-respect, against ourselves. Every crime is against Allah, His creatures, and ourselves, but some may be viewed more in relation to one than to another. The prohibition against taking life is qualified: "except for just cause": e.g., in judicial punishment for murder, or in self-preservation, which may include not only self-defense in the legal sense, but also the clearing out of pests, and the provision of meat under conditions of Halal: see n. 698 to 5:5. After this comes a long parenthesis, which ends with verse 71, of same Surah.
[Tafseer] of Ayat 69. (But) the Penalty on the Day of Judgment will be doubled to him, and he will dwell therein in ignominy,- The three crimes just mentioned are specially detestable and infamous, and as ignominy will be added to other punishments, the penalty will be double that of ordinary punishment.
