Then they conquered them with Lord Allah’s Permission, and Dawood (David) killed Goliath, and Allah gave him kingship and Wisdom and taught him from whatever He wishes; and if Allah hadn’t defended some mankind with others, verily the earth would have been ruined, but Allah is having Bounty upon entire worlds.
During the time of Prophet Samuel as mentioned in the Bible under the leadership of king Twaloot, believers went to fight with Goliath who was the king of Amalek. Dawood joined with the believers on their way to the battlefield. The young Dawood killed the giant Goliath in the dual fight. Thus, the army of Goliath had been defeated. Then the Lord gave kingship and Wisdom (the Book Psalm) to Dawood and thereby He blessed those people. His son Suleiman (Solomon) was also a Prophet and king blessed by wealth, prowess, and dignity which were not given to anyone else in the world.
It is the way of the Lord to defend one set of people using another to keep the earth in its statuesque as told in verse 22: 40. Since today Adhikr which is the Balance and Trust to keep the universe in its equilibrium is formed, the Lord has become Impartial. So, the odd believer will propagate Adhikr to the entire mankind. Since the believer is holding fast the Safeguard Adhikr, nothing in the universe can harm him. Messenger Noah sought forgiveness to Lord upon believers and sought to increase difficulties and disasters upon the wrongdoing disbelievers as told in verses 71: 26-28.
The Arabic Quran reading Fujjar by hiding and rejecting Adhikr are living by fearing worldly matters. So, they will be dragged prone on their faces into Hell, they are in the worst place, and they are the most strayed as told in verses 17: 97-98 and 25: 34. When other people belonging to Messenger Muhammad’s community also become wrongdoers like the Fujjar mentioned in verses 6: 47; 7: 40 and 10: 17, Doomsday will happen. See explanation 1: 1 and 2: 75.
