It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Recite the Qur'an correctly, with its proper vowel endings and grammar, and seek out its rare (unusual and uncommon) words and meanings." This hadith has a sahih (authentic) chain of narration according to the view of a group of our imams, but the two Shaykhs (Bukhari and Muslim) did not record it.
