Be good to daughters
The Prophet Muhammad said: "Whoever is given daughters, and then is patient with them and treats them well, they will become a shield from the fire of hell." (HR. Al-Bukhari 1418 and Muslim 2629 from Aisyah)
He also said: "Whoever raises two daughters until they grow up, then on the Day of Judgment he and I will be together — (and he showed this by joining his fingers)." (HR. Muslim 2631 from Anas)
At a time when ignorant people avoided or hated their daughters, Allah gave a great reward to those who left that bad tradition behind.
