The supererogatory morning prayer has been narrated from Muhammad, through paths that have reached mass-narration levels – from 19 to over 30 companions – according to Imam al-Tabari, al-`Ayni in `Umdat al-Qari, al-Haytami, al-Munawi, and al-Qari in Sharh al-Shama'il, Ibn Hajar in Fath al-Bari, al-Kattani in Nazm al-Mutanathir, and as per the monographs compiled by al-Hakim and al-Suyuti as well as the recensions of Abu Zur`a al-`Iraqi in Tarh al-Tathrib, Ibn al-Qayyim in Zad al-Ma`ad, and al-Shawkani in Nayl al-Awtar. According to the vast majority of the Ulema of the Salaf and Khalaf it is a desirable and recommended prayer.
