Surah Al-Baqarah, verse 158
Emphasis on the three main points:
:اِنَّ الصَّفَا وَا لْمَرْوَةَ مِنْ شَعَآئِرِ اللّٰهِ ۚ فَمَنْ حَجَّ الْبَيْتَ اَوِ اعْتَمَرَ فَلَا جُنَا حَ عَلَيْهِ اَنْ يَّطَّوَّفَ بِهِمَا ۗ وَمَنْ تَطَوَّعَ خَيْرًا ۙ فَاِ نَّ اللّٰهَ شَا كِرٌ عَلِيْمٌ

Safa and Marwah are sacred symbols of Allah are not an ordinary places—they are acts of worship established by Allah Himself.

Performing Sa‘i between them is part of Hajj and Umrah.This verse clarifies that there is no sin in walking (sa‘i) between Safa and Marwah. This was revealed because some early Muslims hesitated due to past pagan associations at those places.

Allah corrected this misunderstanding: Sa‘i is a legitimate and blessed act of worship for anyone performing Hajj or Umrah.Today, sa‘i is obligatory (wājib) and a crucial part of both rituals.

Allah appreciates voluntary good deeds.The verse ends with two beautiful Names of Allah:
(Sukur) — “Appreciative”: Allah values even the smallest good deed done sincerely.

(Elem) — “All-Knowing”: He knows the intention behind every action

Any extra good you do in the Haram, during Hajj/Umrah, or in life in general, is rewarded generously by Allah.

Summary in Simple Words
Allah is telling us: Safa and Marwah are sacred. Sa‘i between them is an honoured act of worship in Hajj and Umrah. And whoever does good—whether compulsory or voluntary—Allah appreciates it and rewards it fully.
