Surah Al-Mujadila, Verse 4

فَمَن لَّمۡ يَجِدۡ فَصِيَامُ شَهۡرَيۡنِ مُتَتَابِعَيۡنِ مِن قَبۡلِ أَن يَتَمَآسَّاۖ فَمَن لَّمۡ يَسۡتَطِعۡ فَإِطۡعَامُ سِتِّينَ مِسۡكِينٗاۚ ذَٰلِكَ لِتُؤۡمِنُواْ بِٱللَّهِ وَرَسُولِهِۦۚ وَتِلۡكَ حُدُودُ ٱللَّهِۗ وَلِلۡكَٰفِرِينَ عَذَابٌ أَلِيمٌ٤

faman lam yajid faṣiyāmu shahrayni mutatābiʿayni min qabli an yatamāssā faman lam yastaṭiʿ fa-iṭ'ʿāmu sittīna mis'kīnan dhālika litu'minū bil-lahi warasūlihi watil'ka ḥudūdu l-lahi walil'kāfirīna ʿadhābun alīmun

And he who does not find [a slave] - then a fast for two months consecutively before they touch one another; and he who is unable - then the feeding of sixty poor persons. That is for you to believe [completely] in Allāh and His Messenger; and those are the limits [set by] Allāh. And for the disbelievers is a painful punishment.
