Bukhari

Mujahid said the meaning of «تفيضون‏» is what you utter with your tongue, what you say. Some have said «أثرة» and «أثرة» (with a dhamma on the hamza) and «أثارة» (all three are qira’at) mean the remaining knowledge. (From this, the word «أثر» is used for the hadith, meaning it is the remaining knowledge of the Prophet, peace be upon him.) And Ibn Abbas, may Allah be pleased with them both, said the meaning of «بدعا من الرسل‏» is that I am not the first messenger to come to the world. Others have said in «أرأيتم‏» (Al-Ahqaf: 4) the hamza is for rebuke and reprimand. That is, if your claim is true, then tell about these things which you worship besides Allah—have they created anything? «احقاف» was the name of the land of the people of ‘Ad where Hud, peace be upon him, was sent. «احقاف», «حقف» is the plural. «مطلق» refers to a mountain of sand. Upon this people, a punishment of a strong wind came with clouds, by which all were destroyed.

Narrated Yusuf bin Mahak: Marwan had been appointed as the governor of Hijaz by Muawiya. He delivered a sermon and mentioned Yazid bin Muawiya so that the people might take the oath of allegiance to him as the successor of his father (Muawiya). Then `Abdur Rahman bin Abu Bakr told him something whereupon Marwan ordered that he be arrested. But `Abdur-Rahman entered `Aisha's house and they could not arrest him. Marwan said, "It is he (`AbdurRahman) about whom Allah revealed this Verse:-- 'And the one who says to his parents: 'Fie on you! Do you hold out the promise to me..?'" On that, `Aisha said from behind a screen, "Allah did not reveal anything from the Qur'an about us except what was connected with the declaration of my innocence (of the slander).
