YUSUF ALI: The mothers shall give such to their offspring for two whole
years, if the father desires to complete the term. But he shall bear the
cost of their food and clothing on equitable terms. No soul shall have a
burden laid on it greater than it can bear. No mother shall be treated
unfairly on account of her child. Nor father on account of his child, an
heir shall be chargeable in the same way. If they both decide on weaning,
by mutual consent, and after due consultation, there is no blame on them.
If ye decide on a foster-mother for your offspring, there is no blame on
you, provided ye pay (the mother) what ye offered, on equitable terms. But
fear Allah and know that Allah sees well what ye do.
PICKTHAL: Mothers shall suckle their children for two whole years; (that
is) for those who wish to complete the suckling. The duty of feeding and
clothing nursing mothers in a seemly manner is upon the father of the
child. No-one should be charged beyond his capacity. A mother should not be
made to suffer because of her child, nor should he to whom the child is
born (be made to suffer) because of his child. And on the (father's) heir
is incumbent the like of that (which was incumbent on the father). If they
desire to wean the child by mutual consent and (after) consultation, it is
no sin for them; and if ye wish to give your children out to nurse, it is
no sin for you, provide that ye pay what is due from you in kindness.
Observe your duty to Allah, and know that Allah is Seer of what ye do.
SHAKIR: And the mothers should suckle their children for two whole
years for him who desires to make complete the time of suckling;
and their maintenance and their clothing must be borne by the
father according to usage; no soul shall have imposed upon it a
duty but to the extent of its capacity; neither shall a mother be
made to suffer harm on account of her child, nor a father on
account of his child, and a similar duty (devolves) on the
(father's) heir, but if both desire weaning by mutual consent and
counsel, there is no blame on them, and if you wish to engage a
wet-nurse for your children, there is no blame on you
so long as you pay what you promised for according to usage;
and be careful of (your duty to) Allah and know that Allah sees
what you do.
