(We have already explained in minute details in this connection in commentary, upon verse 114 of Surah Hūd, No. 11) At any rate, undoubtedly the details as for the five-times daily prayers have not been explained in full in these verses; on the contrary, as is the case with other Islamic commandments, the explanations are confined to the general rules, and their fuller explanations are left to the practice of the Prophet (S) and the true Imams.
Another point which remains outstanding in here is that the above verse says that the ‘morning prayer is being witnessed’. Now this question arises as by whom is it being witnessed?
According to the Islamic quotations received through the commentaries upon this verse suggest that ‘ They are witnessed by both the angels of night and day ’, for, ‘ night angels ’, who are on guard by night, are replaced by day angels at dawn and as morning prayer is performed at dawn, both groups of angels observe and bear testimony to that.
These quotations are quoted by both the Shi‘ah and Sunni scholars, among whom, (according to Tafsir-Rūh-ul-Ma‘ani), Ahmad and Nisa’i, Ibn Majid, Tarmuzi, and Hakim have quoted the Prophet (S) who stated in his commentary upon this sentence: “Both the day and the night angels watch him [^5] .” The famous scholars of Hadith of the Sunnis, Bukh ari and Muslim have also quoted this meaning in their ‘Sahih’.
“And some part of the night keep vigil for it as an additional prayer for you; maybe that your Lord will raise you up to a praised position.” Pursuing the aforegoing theme of the five-time compulsory daily prayers, the Qur’an adds as follows: “And some part of the night keep vigil for it…” The well-known Islamic commentators regard these holy words as allusions made to ‘the supererogation of the night’ when quotations are innumerable as to their virtues, though the holy verse does not explicitly refer to it as such.
Nevertheless, considering all the circumstantial evidences which are usually available, this interpretation seems transparent.
