Recitation of Surah Ash-Shams wa Duhaha in the `Isha' Prayer The Hadith of Jabir which was recorded in the Two Sahihs has already been mentioned. In it the Messenger of Allah ﷺ said to Mu`adh,

«هَلَّا صَلَّيْتَ بِــ

سَبِّحِ اسْمَ رَبِّكَ الاّعْلَى

The fourth oath is taken thus:

وَاللَّيْلِ إِذَا يَغْشَاهَا (and by the night when it envelops him,...91:4). In other words, when it [ the night ] sets in, the brightness of the sun is concealed [ and only darkness prevails ].
