Surah Al Baqarah Ayat 185 in Arabic, Transliteration, and English Translation
Syahru ramaḍānallażī unzila fīhil-qur`ānu hudal lin-nāsi wa bayyinātim minal-hudā wal-furqān, fa man syahida mingkumusy-syahra falyaṣum-h, wa mang kāna marīḍan au ‘alā safarin fa ‘iddatum min ayyāmin ukhar, yurīdullāhu bikumul-yusra wa lā yurīdu bikumul-‘usra wa litukmilul-‘iddata wa litukabbirullāha ‘alā mā hadākum wa la’allakum tasykurụn
“The month of Ramadan is the (month) in which the Qur’an is derived, as a guide for man and explanations of that instruction and a distinction (between the true and the vanity). Therefore, whoever among you is in the month, then fast. And whoever is sick or on the way (he does not fast), then (is obliged to replace it), as many days as he leaves, on other days. God desires ease for you, and wills no hardship for you. Let ye suffice-give of his numbers and glorify God for his instructions given to you, that ye may be grateful.” (Q.S Al Baqarah : 185)
The month of Ramadan is the month in which for the first time the Qur’an derives on lailatul qadar, that is, the night of glory, as a guide for man and explanations of that instruction and the distinction between right and wrong. Therefore, whoever among you is, that is, alive, in that month in a state of old age, then fast. And whoever is sick among you or on the way and chooses not to fast, then he is obliged to replace it as much as the day he left on other days. God desires ease for you by allowing iftar, and does not want hardship for you by still obliging fasting in sickness or on the way. Let you sufficiency the number by fasting a whole month and ending the fast by glorifying God for His instructions given to you, that you may be grateful for it.
