It is better that in the second Rak`at of the first Salat, Surah al-Muzzammil is read and in the second Rak`at of the second Salat, Surah an-Naba is read. It is Mustahab that in the first Rak`at of the third Salat, Surah Ya Sin is read, and in the second Rak`at (of the third Salat), Surah ad-Dukhan is read – alternately, one can read Surah Waqiyah in place of Ya Sin and Surah al-Muddathir in place of Surah ad-Dukhan.
It is Mustahab that in the first Rak`at of the fourth Salat, Surah al-Mulk is read and in the second Rak`at of the fourth Salat, Surah al-Insan is read.[^8] It has been mentioned that Imam Muhammad ibn `Ali al-Baqir (peace be upon him) used to recite Surah al-Ikhlas in the Salat al-Shaf` and Salat al-Witr and after reciting this Surah, would say: كَذٌالِكَ اللٌّهُ رَبِّي “This is Allah my Lord” [^9] Recitation of Surah al-Ikhlas is counted as the recitation of one-third of the Qur`an, thus, who ever recites this Surah in the three Rak*` at ( Salat al-Shaf `* and Salat al-Witr) is as if he has recited the entire Qur`an.[^10] [^1]: Bihar Al-Anwar, Vol.
