Question: Is the corruption of children [through poor nurturing considered as] a tribulation?
Response: Yes, children are a tribulation, [as Allaah (‘Azza wa Jall) says]:
{And know that your properties and your children are but a trial}, soorah al-Anfaal, aayah 28
…meaning that they are a tribulation and a test; [ask yourself] are you nurturing them well, being patient with them and upholding your duty to them and giving them their rights or not? So [yes], they are a tribulation.
