Sura al-Baqara 2:158

إِنَّ ٱلصَّفَا وَٱلْمَرْوَةَ مِن شَعَآئِرِ ٱللَّـهِ فَمَنْ حَجَّ ٱلْبَيْتَ أَوِ ٱعْتَمَرَ فَلَا جُنَاحَ عَلَيْهِ أَن يَطَّوَّفَ بِهِمَا وَمَن تَطَوَّعَ خَيْرًا فَإِنَّ ٱللَّـهَ شَاكِرٌ عَلِيمٌ

inna l-ṣafā wa-l-marwata min shaʿāʾiri allāhi fa-man ḥajja l-bayta awi ʿtamara fa-lā junāḥa ʿalayhi an yaṭṭawwafa bihimā wa-man taṭawwaʿa khayran fa-inna allāha shākirun ʿalīmun

Behold! Safa and Marwa are among the Symbols of Allah. So if those who visit the House in the Season or at other times, should compass them round, it is no sin in them. And if any one obeyeth his own impulse to good,- be sure that Allah is He Who recogniseth and knoweth.

Sura al-Baqara 2:184

أَيَّامًا مَّعْدُودَٰتٍ فَمَن كَانَ مِنكُم مَّرِيضًا أَوْ عَلَىٰ سَفَرٍ فَعِدَّةٌ مِّنْ أَيَّامٍ أُخَرَ وَعَلَى ٱلَّذِينَ يُطِيقُونَهُۥ فِدْيَةٌ طَعَامُ مِسْكِينٍ فَمَن تَطَوَّعَ خَيْرًا فَهُوَ خَيْرٌ لَّهُۥ وَأَن تَصُومُوا۟ خَيْرٌ لَّكُمْ إِن كُنتُمْ تَعْلَمُونَ

ayyāman maʿdūdātin fa-man kāna minkum marīḍan aw ʿalā safarin faʿiddatun min ayyāmin ukhara wa-ʿalā lladhīna yuṭīqūnahu fidyatun ṭaʿāmu miskīnin fa-man taṭawwaʿa khayran fa-huwa khayrun lahu wa-an taṣūmū khayrun la-kum in kuntum taʿlamūna

(Fasting) for a fixed number of days; but if any of you is ill, or on a journey, the prescribed number (Should be made up) from days later. For those who can do it (With hardship), is a ransom, the feeding of one that is indigent. But he that will give more, of his own free will,- it is better for him. And it is better for you that ye fast, if ye only knew.
