بِسْمِ اللَّـهِ الرَّحْمَـٰنِ الرَّحِيمِ

Muslims in different parts of the world have different practices between two rakats of Taraweeh like some say:

سبحان ذي الملك والملكوت، سبحان ذي العزة والعظمة والهيبة والكبرياء والجبروت، سبحان الحي الذي لا يموت، سبوح قدوس رب الملائكة والروح

others prefer: لا إله إلا الله وحده لا شريك له، له الملك وله الحمد، يحيي ويميت، وهو على كل شئ قدير

some also recites Surah Al-Ikhlas and Darood.

No doubt that all these are good deeds in themselves. However, it is worth noting that saying these Dhikrs or Duas or recitations is not narrated in any Hadith or action of a companion of the Prophet. Hence, this comes in the circle of innovation and Bid’ah and therefore it is necessary to avoid this as the Messenger of Allah says:

مَن أَحْدَثَ في أَمْرِنَا هذا ما ليسَ فِيهِ فَهو رَدّ

“Whoever introduces into our religion that is not a part of it is rejected”

[Muttafaqun ‘Alaih, Sahih Bukhari:2697, Sahih Muslim:1718]

واللہ اعلم بالصواب
