(71) Say (O Muhammad صلى الله عليه و سلم): "If the Most Gracious (Allah) had a son (or children as you pretend), then I am the first of Allah's worshippers [who deny and refute this claim of yours (and the first to believe in Allah Alone and testify that He has no children)]." [Tafsir At-Tabari].

(72) Then We have put you (O Muhammad صلى الله عليه و سلم) on a (plain) way of (Our) commandment [like the one which We commanded Our Messengers before you (i.e. legal ways and laws of the Islamic Monotheism)]. So follow you that (Islamic Monotheism and its laws), and follow not the desires of those who know not. (Tafsir At-Tabari).

(73) And during a part of the night (also) glorify His praises (i.e. Maghrib and 'Isha prayers) and (so likewise) after the prayers [As-Sunnah, Nawafil - optional and additional prayers. And also glorify, praise and magnify Allah - Subhan Allah, Alhamdu lillah, Allahu-Akbar].

(74) Then his wife came forward with a loud voice: she smote her face, and said: "A barren old woman!"

(75) And in 'Ad (there is also a sign) when We sent against them the barren wind;

(76) "Verily, We used to invoke Him (Alone and none else) before. Verily, He is Al-barr (the Most Subtle, Kind, Courteous, and Generous), the Most Merciful."

(77) And verily, for those who do wrong, there is another punishment (i.e. the torment in this world and in their graves) before this; but most of them know not. (Tafsir At-Tabari).

(78) Between them is a barrier which none of them can transgress.

(79) But We (i.e. Our angels who take the soul) are nearer to him than you, but you see not, (Tafsir At-Tabari)

(80) And (O Muhammad صلى الله عليه وسلم) obey you not everyone Hallaf Mahin (the one who swears much and is a liar or is worthless). [Tafsir At-Tabari]
