What is the meaning of the following words in the Quran: "Yaṣdifūn" (يصدفون), "Kalālah" (كلالة), "Mushtabih" (مشتبه), and "Al-Falaq" (الفلق)?

The word "yasdifūna" (يصدفون) means to turn away from the truth and hinder its pursuit. It appears in Surat Al-An'am (The Cattle), in the verse: {See how We diversify the signs; yet they turn away} (6:65). "Al-Kalalah" (الكلالة) refers to someone who has neither children nor parents among their heirs. The word "mushtabih" (مشتبه) in the verse: {similar and dissimilar} (6:99) could refer to pomegranates and olives, meaning their trees are similar while their fruits differ, or it could refer to all trees and fruits, where some are similar and others are dissimilar. As for "Al-Falaq" (الفلق), it means the dawn, which is the correct interpretation chosen by Al-Bukhari. It was also said to mean creation or a house in Hell.
