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. Anas ibn Malik ^Rz reported: The Messenger of Allah ^PBUH said when the month of Ramadan began:
إِنَّ هَذَا الشَّهْرَ قَدْ حَضَرَكُمْ وَفِيهِ لَيْلَةٌ خَيْرٌ مِنْ أَلْفِ شَهْرٍ مَنْ حُرِمَهَا فَقَدْ حُرِمَ الْخَيْرَ كُلَّهُ وَلَا يُحْرَمُ خَيْرَهَا إِلَّا مَحْرُومٌ
Verily, this month has presented itself to you. There is a night within it that is better than a thousand months. Whoever is deprived of it has been deprived of all good. None is deprived of its good but that he is truly deprived.

Hazrath Imam Mahdi al-Mauood ^PBUH held the skin of his body with two of his fingers and said that- “This flesh and skin is of this slave (of Allah); whoever rejects the Mahdi-ship (Mahdiat) of this person (zath) is a kafir.”

Hazrat Ali -ul Murtuza ^Rz said that:Contentment is an asset which is never exhausted.
