Sunna of tilwa: when reciting the Quran’s chapters 93 to 114:

It is a sunna to say takbir with recitation of each chapter from surah 93 till the end of Quran al-kareem. Shaykh Ahmad Salih al-Misri has narrated the wordings of this takbir as,

لا اله الا الله و الله اكبر

Ibn Khathir said that it a sunna to recite it at the end of every chapter and Bagwi said at the beginning. Acting on either of these will be according to sunna.
