As the words of Aisha say,

May Allah be pleased with her, the verse has been revealed to remove all false ideas on this subject and to eliminate any embarrassment experienced by the Muslims vis-à-vis the Sa'y between As -Safa and Al-Marwah, at a place where idols were worshiped during the Djaahiliyyah. Thus, Allah, Exalted be He, did not reveal this verse to show that this rite was not obligatory, contrary to what might suggest the style of the verse.

 In another narrative, 'Aisha, May Allah be pleased with her, said:' The Prophet (peace and blessings of Allaah be upon him) has instituted the Sa'y between As-Safa and Al-Marwah. So no one is allowed to neglect it. "(Bukhari and Muslim)

 In addition, the negative form of the phrase “do not commit sin ", linked to the Sa'y between As-Safa and Al-Marwah during Hajj or Umrah, means that this ritual can not be accomplished separately from these Two acts of worship, unlike the Tawaaf, circumambulation, which can be accomplished without being bound to the accomplishment of a Hajj or an 'Umrah.     

“And whosoever willingly doeth a good work, " that is, obedience, " then Allah is Grateful, Omniscient, " that is to say, will give him the reward of that obedience which does not escape Him Never, Exalted be He.

 Thus, Allah, Exalted be He, emphasized that the greatest benefits result from the obedience and good works that bring the servant of Allah closer to his Lord, Exalted be He, for the more the servant obeys his Creator, the more the good and the perfection that are in him increase, and the higher his rank rises in the eyes of Allah, Exalted be He.
