An-Nasa'i recorded that `Abdullah bin `Umar, may Allah be pleased with him, said, "The Messenger of Allah ﷺ used to command us to make our prayers short and he used to recite As-Saffat when he lead us in prayer." This was recorded by An-Nasa'i only.
بِسْمِ اللَّهِ الرَّحْمَـنِ الرَّحِيمِ
In the Name of Allah, the Most Gracious, the Most Merciful.
It was reported that `Abdullah bin Mas`ud, may Allah be pleased with him, said:
وَالصَّـفَّـتِ صَفَّا
"(By those ranged in ranks.) -- they are the angels;
فَالزَجِرَتِ زَجْراً
(By those who drive the clouds in a good way. ) they are the angels;
It was said: رَّبُّ السَّمَاوَاتِ وَالْأَرْضِ وَمَا بَيْنَهُمَا وَرَبُّ الْمَشَارِقِ (the Lord of the heavens and the earth and what is between them, and Lord of the points of the sunrise. - 37:5). Now, a Being to whom goes the credit of having created and sustained such a mind-boggling range of creations has to be the One most deserving of ownership. And this entire universe is a positive proof of His existence and Oneness. The word: الْمَشَارِقِ (al-mashariq) as used here is the plural form of مَشرِق mashriq or East. Since, the sun rises from a new point every day of the year, therefore, its orientations in the East are many, and it is on this basis that the plural form has been employed here.
Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 5–9
One of the secrets revealed through the Prophet is the existence of angels. Here, three special aspects of the angels have been mentioned. First, they are completely obedient to God. Without the slightest hesitation or objection, they carry out His orders. Then there is a group of angels which implements the punishments imposed by God on human beings, either in the shape of calamities or untoward incidents or in any other manner dictated by Him. The angels also bring God’s advice to man in the form of inspiration or intuition (ilham) and as revelation (wahi) to the prophets.
