Saba 34:42

So Today none of you has the power to benefit or harm one another. And We will say to the wrongdoers, “Taste the punishment of the Fire which you used to deny!”

But today [i.e., the Day of Judgement] you do not hold for one another [the power of] benefit or harm, and We will say to those who wronged, "Taste the punishment of the Fire, which you used to deny."

42. So Today (i.e. the Day of Resurrection), none of you can profit or harm one another. And We shall say to those who did wrong [i.e. worshipped others (like the angels, jinn, prophets, saints, righteous persons) along with Allâh]: "Taste the torment of the Fire which you used to belie.[3]

[3] (V.34:42) Almighty Allâh says: "They (Jews and Christians) took their rabbis and their monks to be their lords (by obeying them in things that they made lawful or unlawful according to their own desires without being ordered by Allâh) besides Allâh, and (they also took as their Lord) Messiah, son of Maryam (Mary), while they (Jews and Christians) were commanded [in the Taurât (Torah) and the Injeel (Gospel)] to worship none but one llâh (God - Allâh), Lâ ilâha illâ Huwa (none has the right to be worshipped but He). Praise and Glory is to Him, (far above is He) from having the partners they associate (with Him)." [The Qur’ân, Verse 9:31]
Once, while Allâh’s Messenger صلى الله عليه وسلم was reciting the above Verse, ‘Adi bin Hâtim said, "O Allâh’s Prophet! They do not worship them (rabbis and monks)." Allâh’s Messenger صلى الله عليه وسلم said, "They certainly do. They (i.e. rabbis and monks) made legal things illegal, and illegal things legal, and they (i.e. Jews and Christians) followed them, and by doing so they really worshipped them." [Narrated by Ahmad, At-Tirmidhi, and Ibn Jarir. (Tafsîr At-Tabarî, Vol.10, Page No.114)].

That day ye will possess no use nor hurt one for another. And We shall say unto those who did wrong: Taste the doom of the Fire which ye used to deny.
