وَٱلْفُرْقَانِ ۚ فَمَن شَهِدَ مِنكُمُ ٱلشَّهْرَ فَلْيَصُمْهُ ۖ وَمَن كَانَ مَرِيضًا أَوْ عَلَىٰ سَفَرٍ فَعِدَّةٌ مِّنْ أَيَّامٍ أُخَرَ ۗ يُرِيدُ ٱللَّهُ بِكُمُ ٱلْيُسْرَ وَلَا يُرِيدُ بِكُمُ ٱلْعُسْرَ وَلِتُكْمِلُوا۟ ٱلْعِدَّةَ وَلِتُكَبِّرُوا۟ ٱللَّهَ عَلَىٰ مَا هَدَىٰكُمْ وَلَعَلَّكُمْ تَشْكُرُونَ
The month of Ramazan[is that] in which was revealed the Qur’an, a guidance for the people and clear proofs of guidance and criterion. So whoever sights [the new moon of] the month, let him fast it; and whoever is ill or on a journey – then an equal number of other days. Allah intends for you ease and does not intend for you hardship and [wants] for you to complete the period and to glorify Allah for that [to] which He has guided you; and perhaps you will be grateful.
Surah Baqarah Ayat 185.

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.

Imam Mahdi,The Promised ^PBUH is narrated to have said that-“Whatever the voice (command) of Allah this servant (banda) hears by his ears,he conveys it to you by the word of mouth.Whether you obey the commands or not is your business.That is between you and Allah.”

Ameer Ul Mumineen Hazrath Ali Ul Murtuza ^Rz. said that – “Verily, there are three (types of) friends for a Muslim, The friend who says: I am with you whether you are alive or dead, and this is his deed. The friend who says: I am with you unto the threshold of your grave and then I will leave you, and this is his children. The friend who says: I will be with you until when you die, and this is his wealth which will belong to the inheritors when he dies.”
