The Cow - 2:116
"They said: "Allah has taken a child". Glory be to Him. To Him belongs all that is in the heavens and the earth, and to Him all is subject."
The gravity of ascribing children to Allah:
Mary/19:88
"They even said: "The Most Merciful has taken a child"
Mary/19:89
You have put forward an arrogant argument.
Mary/19:90
Because of this arrogance, almost the heavens will be torn asunder, the earth will split and the mountains will collapse.
Mary/19:91
Because they ascribed a child to the Most Merciful.
Mary/19:92
It does not befit the Most Merciful to have children.
Mary/19:93
Whoever is in the heavens and the earth will come to the Most Merciful as a servant.
