{And O my people, indeed I fear for you the Day of Calling.}

He frightens them with the punishment of the Hereafter after having frightened them with the punishment of this world. At-Tanad (the Calling) is a verbal noun derived from tanada the people, meaning they call out to one another. The "Day of Calling" is the Day of Resurrection, named as such because people will call out to one another for help, or they will cry out to one another in woe and destruction, or because of the calling between the people of Paradise and the people of Hell—as related in Surah Al-A'raf—or because all of creation will be called to the place of assembly, or due to the believer’s call: "Here, read my record," and the disbeliever's call: "I wish I had not been given my record."

It is reported from Ibn Abbas that this calling occurs among people at the blowing of the Horn and the blast of terror in this world, whereby they flee upon their faces due to the terror that has befallen them, calling out to one another. This has also been narrated from Abu Hurairah, from the Prophet (may Allah exalt his mention and grant him peace).

Ibn Atiyyah said: It is possible that it is intended to recall every calling in the Hereafter that involves hardship for the disbelievers and the disobedient.

A group recited At-Tanad with a silent dal during connection, treating it as if it were a pause. Ibn Abbas, Ad-Dahhak, Abu Salih, Al-Kalbi, Az-Za'farani, and Ibn Miqsam recited At-Tannad with the dal emphasized (shaddah), derived from nada (the camel ran away), meaning the Day of Flight and Escaping, based on the saying of the Exalted: "The day a man will flee from his brother," and the verse. In the Hadith, it is mentioned that people will have a circuit on the Day of Resurrection, running away, thinking they will find an escape.

It is also said: The intent is the Day of Gathering, from nada when one gathers, and from this comes the word an-nadi (the gathering place/club).
