Marking tenths in the mushaf

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) disliked ta'shir in the mushaf. (Ta'shir of the Qur'an means placing a mark after every ten verses; dividing it into parts, juz', quarters, halves and thirds is of the same kind. The early generations disliked this because they feared that, through such marginal additions, things that are not in fact part of the Qur'an would become part of it. When this fear ended, the dislike also ended, and for many years now Muslims have practised ta'shir.)

Ata used to dislike ta'shir in the mushaf, and also that anything other than the Qur'an be written in it.

Something similar is reported from Ibrahim.

Mujahid used to dislike that ta'shir or section dividers be written in the mushaf, or that one say "Surat al-Baqarah"; rather, he would say "the surah in which the cow is mentioned."

Ata used to dislike ta'shir in the mushaf, and also that anything other than the Qur'an be written in it.

Al-Zibriqan said: I said to Abu Razin: I have a mushaf which I want to embellish with gold, and at the beginning of every surah I want to write that it has so many verses. Abu Razin said: Do not add anything of this world to the Qur'an, little or much.

Hisham said: Muhammad (Ibn Sirin) used to dislike the surah headings (fawatih) and tenth-verse markers (awashir) containing qaf and kaf.

Sayyiduna Abdullah (may Allah be pleased with him) once saw a line drawn in a mushaf, so he scraped it off and said: Do not mix into the Qur'an what is not Qur'an.

Ibrahim disliked ta'shir in the mushaf.

Mujahid disliked ta'shir in the mushaf.

Ibrahim disliked dots in the Qur'an and writing "the end of Surah so-and-so."

Sayyiduna Ibn Mas'ud (may Allah be pleased with him) said: Keep the Qur'an free of what is not Qur'an, and do not mix into it what is not part of it.

Ibrahim said: It used to be said: Keep the Qur'an free of what is not Qur'an.

Sayyiduna Abdullah (may Allah be pleased with him) said: Keep the Qur'an free of what is not Qur'an.

Al-Hasan bin Ubaydullah said: I said to Abd al-Rahman bin al-Aswad: What prevented you from asking as Ibrahim asked? He said: It used to be said: Keep the Qur'an free of what is not Qur'an.

Abu al-Aliyah used to dislike phrases being written in the mushafs at the opening and the close (of surahs), and he would say: Keep the Qur'an free of what is not Qur'an.
