They are saying: “Lord Allah has taken a son”. Exalted is He; He is Self-Sufficient. To Him belongs whatever is in the heavens and whatever is on the earth. Do you have any authority for this; are you saying about Allah with what you don’t know?
All the 313 Messengers were sent with Adhikr—the Proof and Truth—to inform mankind that there is no deity except Allah, and so you serve Him alone as told in verses 16: 2 and 21: 24-25. Verses 22: 8 and 31: 20 said: “There are some among mankind who are arguing in the case of Lord Allah without Knowledge, Guidance and the Enlightening Book”. It is told in verses 35: 24-25: “Lord has sent Messengers to every community with Adhikr as Warner and Herald. So, if these people reject you, then surely, those before them also rejected the Messengers who came with Explanations, Scriptures and Enlightening”. Adhikr revealed to Messenger Muhammed contains all 312 Books and their upright Explanations to explain to mankind what has been revealed for them Book so that they may think and reflect It to others as told in verse 16: 44.
Today, these verses are only read by the Fujjar among mankind. So, it is their inevitable duty to submit Lord as the Only Deity as well as the King of whole mankind as explained in 10: 65. But by hiding and rejecting Adhikr—the Real Knowledge, these true disbelievers as explained in verses 4: 150-151 are serving Satan and are following his footsteps as explained in verses 2: 168-169. All their deeds are in vain since they are following falsehood by ignoring Adhikr-the Truth-as told in verse 17: 81. The disbelieving and wrongdoing Mujirims, as well as their followers, will curse, blame and argue against each other in Hell as explained in verses 2: 165-167. See explanation 2: 116-117; 6: 100 and 9: 30-31.
