The Cattle - 6:152
Do not approach the property of orphans until they reach the age of maturity. Measure and weigh accurately. We do not burden a person with what he is not able. When you speak, be truthful even against your relatives. Keep your promise to Allah. These are His admonitions to you that you may take a lesson.

The Cow/2:286
"Allah burdens each person only up to his capacity. The good that each person earns is for his own benefit and the evil that he earns is for his own loss. "Our Lord, do not hold us responsible if we forget or err! Our Lord, do not burden us with burdens as You burdened those before us! Our Lord, do not burden us with what we are not able to bear; forgive us and have pity on us! You are our Mawla (master and sovereign). Help us against the community of disbelievers!"

The Cow/2:233
For those who wish to complete the period of breastfeeding, mothers should breastfeed their babies for two years. The mother´s need for food and clothing should be met by the father of the child in a good and proper manner. No one should be held responsible beyond his capacity. The mother should not be harmed because of her child, nor should the father be harmed because of his child. It is also the duty of the heir to realize this. If the parents want to wean after consultation and agreement, there is no sin on either of them. If you wish to have your children suckled by a wet nurse, you are not liable as long as you pay her properly. Listen to Allah, Allah is All-Seeing of what you do.
The Believers/23:62
