You ask: "Shall we appeal besides Lord Allah that can neither benefit us nor harm us and shall we turn on our heels after Allah has guided us", just like the one whom Satan has enticed away in the earth while he has companions calling him into the Guidance: "You Come to us!" You say: "Indeed, the Guidance of Allah is the only Guidance, and we are commanded to submit ourselves wholly to the Lord of the Worlds".
The Messenger and believers are commanded to appeal only to Lord and to remind mankind about Him in their heart’s language as told in verse 32: 4. But today Arabic Quran reading Fujjar who have inherited Lord's Book are neither utilizing It nor giving It to others. The human devil hypocrites among Fujjar are converting Lord’s favors into disbelief and have made permissible Hell for their blind followers as explained in verse 5: 88. The Fujjar are compared to a dog that will not change its attitude whether disturbed or not as explained in verse 7: 175-176.
Adhikr is the Guidance mentioned in 80 places such as in verses 2: 2, 38, 185; 7: 52, 203; 16: 44, and 45: 11. Satan will seduce the 999 out of every thousand as explained in verse 4: 118. Only one in a thousand becomes a believer who holdfasts Lord by holding Adhikr, so he is guided into the Straightpath as explained in verse 5: 48. The believer who transforms his Jinns soulmate into a believer with Adhikr can only keep Lord in his heart as explained in verse 3: 102. Lord has sent down Adhikr which explains everything as a Guidance, Mercy, and Herald for the true Muslims who submit wholly to Him as explained in verse 16: 89. See explanation 2: 120- 121, 2: 275, and 3: 193- 194.
