O Allah, I declare strictly inviolable the rights of the two weak ones: the orphan and the woman
Good hadithعن أبي شريح خويلد بن عمرو الخزاعي و أبي هريرة رضي الله عنهما عن رسول الله صلى الله عليه وسلم قال: «اللَّهُمَّ إِنِّي أُحَرِّجُ حَقَّ الضَعِيفَين: اليَتِيم والمَرْأَة».
Abu Shurayh Khuwaylid ibn ‘Amr al-Khuzā‘i and Abu Hurayrah (may Allah be pleased with both of them) reported that the Messenger of Allah (may Allah's peace and blessings be upon him) said: "O Allah, I declare strictly inviolable the rights of the two weak ones: the orphan and the woman."
Explanation
This Hadīth confirms the Islamic principle of gentleness towards the weak, like orphans and women. It is noticed in this Hadīth that the Prophet (may Allah's peace and blessings be upon him) gave extra care to the rights of orphans and women because they have no authority to resort to for defending them. So, he declared that whoever usurps their rights is sinful and exposes himself to suffering difficulty and hardship.
