If Lord Allah is helping you, then none can overcome you; if He is forsaking you, then who is there for helping you after Him? Then upon Allah entrust the believers.
The Lord is with the believer who transforms his Jinn soulmate into a believer with Adhikr and keeps Lord in his heart as explained in verses 3: 101-102. If the Lord who is the Sovereign, Exalted and the Wise helps a group or a person, none can defeat them or him. So the believers should seek help and entrust upon Allah alone whom 6236 verses of Lord's Book submit. The believer who wants to enter in the Paradise should holdfast Adhikr which is the Balance and Trust to keep the universe in its equilibrium and should help the Impartial Lord by propagating It to entire mankind. Lord has taught through His Messenger that no Satanic force can defeat such believers. The believer who testifies Adhikr is having the confirmed belief that anything that Allah has decided for him such as wealth, marriage, children, health, if all people in the world try to prevent, they can't do it; and if any suffering such as accident, disease, death, loss of wealth, etc., if all people in the world try to prevent it, it won't be removed from them/him. That is the meaning of the prayer "Oh Allah! there is no ne to prevent what you give, there is no one to give what you prevent, there is no one to cancel your decree, there is no one to alter your judgement, and the supremacy of any superior won't benefit in front of you". Lord has taught through His Messenger that decree won't be cancelled except with prayer. Two conditions to accept prayer is explained in verse 2: 186. See explanation 2: 155-157; 3: 26-27, 101-103, 125-126; 8: 74 and 9: 50-51.
