The early Muslims called it al-`Asr. The great scholar of Qur’an, al-Tabari, God have mercy on him, narrates with a sound chain from ‘Ubayd Allah the son of Husayn, “Whenever two of the Prophet’s companions would meet, they would not disperse until they read Surah al-‘Asr.” Also, in most of the books dedicated to explaining the Qur’an (al-tafsir), this name is given to the surah (chapter). This is also the case with the existent copies of the Qur’an, new and old- this name is used.
