إِلَّا ٱلَّذِينَ عَٰهَدتُّم مِّنَ ٱلْمُشْرِكِينَ ثُمَّ لَمْ يَنقُصُوكُمْ شَيْـًۭٔا وَلَمْ يُظَٰهِرُوا۟ عَلَيْكُمْ أَحَدًۭا فَأَتِمُّوٓا۟ إِلَيْهِمْ عَهْدَهُمْ إِلَىٰ مُدَّتِهِمْ ۚ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُتَّقِينَ
Excepting those of the idolaters with whom ye (Muslims) have a treaty, and who have since abated nothing of your right nor have supported anyone against you. (As for these), fulfil their treaty to them till their term. Lo! Allah loveth those who keep their duty (unto Him).

Fasting
Chapter: Observing Saum (fasting) daily throughout the life.
Narrated `Abdullah bin `Amr:
Allah's Messenger (ﷺ) was informed that I had taken an oath to fast daily and to pray (every night) all the night throughout my life (so Allah's Messenger (ﷺ) came to me and asked whether it was correct): I replied, "Let my parents be sacrificed for you! I said so." The Prophet (ﷺ) said, "You can not do that. So, fast for few days and give it up for few days, offer Salat (prayer) and sleep. Fast three days a month as the reward of good deeds is multiplied ten times and that will be equal to one year of fasting." The Prophet (ﷺ) said to me, "Fast one day and give up fasting for two days." I replied, "I can do better than that." The Prophet (ﷺ) said to me, "Fast one day and give up fasting for a day and that is the fasting of Prophet David and that is the best fasting." I said, "I have the power to fast better (more) than that." The Prophet (ﷺ) said, "There is no better fasting than that."
