(91) O you wrapped in garments (i.e. Prophet Muhammad صلى الله عليه وسلم)!

(93) And purify your garments!

(94) And their recompense shall be Paradise, and silken garments, because they were patient.

(96) Where they shall neither hear harmful speech nor falsehood.

(97) But the Messenger of Allah [Salih عليه السلام] said to them: "Be cautious! (Fear the evil end). That is the she-camel of Allah! (Do not harm it) and bar it not from having its drink!"

(98) Except those who believe (in Islamic Monotheism) and do righteous good deeds, and recommend one another to the truth [i.e. order one another to perform all kinds of good deeds (Al-Ma'ruf) which Allah has ordained, and abstain from all kinds of sins and evil deeds (Al-Munkar which Allah has forbidden], and recommend one another to patience (for the sufferings, harms, and injuries which one may encounter in Allah's Cause during preaching His religion of Islamic Monotheism or Jihad).

(99) Have you (O Muhammad صلى الله عليه وسلم) not seen how your Lord dealt with the owners of the Elephant? [The Elephant army which came from Yemen under the command of Abrahah Al-Ashram intending to destroy the Ka'bah at Makkah].
