Lawful earnings become difficult as a result of marriage. There is in Hadith that if a man earns virtues to the height of mountain, he shall have to wait near the Balance and accounts will be taken from him of his wealth, of his expenditure, of his maintenance and other matters.
The children will say to Allah on the Resurrection Day: “0 our Lord, take from him the account of his duties towards us, he did not teach us what we did not know and he gave us unlawful food to eat without our knowledge. Take compensation from him for these. The Prophet Sallallahu Alyhi Wa Sallam said: “Nobody will meet Allah with a greeter sin than with a sin of keeping his family members uneducated. Very few people will get release from this danger.”
