It is narrated from Sayyiduna Anas (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Whoever raises two girls until they reach maturity, he and I will enter Paradise (together) like this" - and he (peace and blessings be upon him) pointed with his index and middle fingers. "And there are two sins whose punishment is hastened in this world: al-baghy (rebellion and oppression) and al-'uquq (disobedience to parents)." This hadith is sahih al-isnad (its chain is authentic), but the two Shaykhs (Bukhari and Muslim) did not record it.
