Do reading Surat Al-Waqi'ah, Tabarak, and Ad-Dukhan before sleep suffice for reading the Qur'an in general and for reading the rest of the surahs?

The encouragement to recite Surat Al-Mulk before sleeping is well-established, whereas a weak hadith has been reported concerning the virtue of reciting Surat Al-Waqi'ah every night, and a fabricated hadith regarding the recitation of Surat Ad-Dukhan every night. Reciting these surahs does not substitute for reciting other parts of the Qur'an or completing its recitation. Rather, one should consistently recite and care for the Qur'an, and be cautious of abandoning it. Similarly, one should consistently observe the authentic supplications (adhkar) before sleeping.
