قُلْ أَرَءَيْتُم مَّآ أَنزَلَ ٱللَّهُ لَكُم مِّن رِّزْقٍۢ فَجَعَلْتُم مِّنْهُ حَرَامًۭا وَحَلَٰلًۭا قُلْ ءَآللَّهُ أَذِنَ لَكُمْ ۖ أَمْ عَلَى ٱللَّهِ تَفْتَرُونَ
Say: Have ye considered what provision Allah hath sent down for you, how ye have made of it lawful and unlawful? Hath Allah permitted you, or do ye invent a lie concerning Allah?

Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
"So whoever of you sights (the crescent on the first night of) the month (of Ramadan, i.e., is present at his home), he must observe Saum (fast) that month... (V.2:185)
Narrated Salama:
When the Divine Revelation: "For those who can fast, they had a choice either fast, or feed a poor for every day," (2.184) was revealed, it was permissible for one to give a ransom and give up fasting, till the Verse succeeding it was revealed and abrogated it.
