يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ كُتِبَ عَلَيْكُمُ ٱلصِّيَامُ كَمَا كُتِبَ عَلَى ٱلَّذِينَ مِن قَبْلِكُمْ لَعَلَّكُمْ تَتَّقُونَ
O you who have believed, decreed upon you is fasting as it was decreed upon those before you that you may become righteous
Surah Baqarah Ayat 183

In another narration, the Prophet ^PBUH said:
اللَّهُمَّ أَهِلَّهُ عَلَيْنَا بِالْأَمْنِ وَالْإِيمَانِ وَالسَّلَامَةِ وَالْإِسْلَامِ وَالتَّوْفِيقِ لِمَا تُحِبُّ وَتَرْضَى رَبُّنَا وَرَبُّكَ اللَّهُ
O Allah, bring it over us with safety and faith, security and Islam, guidance to what You love and is pleasing to You. Our Lord and your Lord is Allah.

Imam Mahdi, The Promised ^PBUH is narrated to have said that -“Futuh (charity) is the right of the fuqara (indigents).The people who struggle for food or have Taiyun (fixed periodical income) should not eat out of what is in the right of faqirs (the indigents),because futuh is in the right of the fuqara.People other than the fuqara should not demand a share in what is their right.However,if the Murshid gives them a share,because they live in the daira,they should take it as the right of the neighbours.”

Hazrath Ali Ul Murtuza ^Rz. said that -“To oppress the weak is the worst tyranny.”
