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
[Fasting for] a limited number of days. So whoever among you is ill or on a journey [during them] – then an equal number of days [are to be made up]. And upon those who are able [to fast, but with hardship] – a ransom [as substitute] of feeding a poor person [each day]. And whoever volunteers excess – it is better for him. But to fast is best for you, if you only knew.
Surah Baqarah Ayat 184

Hz. Abu Huraira reported: The Messenger of Allah ^PBUH said:
‏إِذَا دَخَلَ شَهْرُ رَمَضَانَ فُتِّحَتْ أَبْوَابُ السَّمَاءِ وَغُلِّقَتْ أَبْوَابُ جَهَنَّمَ وَسُلْسِلَتِ الشَّيَاطِين‏
When the month of Ramadan begins, the gates of the heaven are opened, the gates of Hellfire are closed, and the devils are chained.

Ameer-Ul-Muminin Hazrath Ali -ul Murtuza ^Rz. ne farmaya ke-“Allah (SWT) ki shaan ye nahi ke dua ka darwaza kholay aur quboliat ka band kar day ya tauba ka darwaza kholay aur maghfirat ka darwaza band kar day.”
