Hadith on Vows: The Prophet discouraged vows which are difficult and worship which is burdensome

Ibn Abbas reported: While the Prophet, peace be upon him, was giving a sermon, he saw a man standing and he asked about him. They said, “It is Abu Israel, who has vowed that he will stand and never sit down, he will never come into the shade nor will he speak to anyone, and he will be fasting.” The Prophet said, “Tell him to speak and let him come into the shade; make him sit down but let him complete his fast.”

[Sahih Bukhari, Book 78, Number 695]

عَنْ ابْنِ عَبَّاسٍ قَالَ بَيْنَا النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ يَخْطُبُ إِذَا هُوَ بِرَجُلٍ قَائِمٍ فَسَأَلَ عَنْهُ فَقَالُوا أَبُو إِسْرَائِيلَ نَذَرَ أَنْ يَقُومَ وَلَا يَقْعُدَ وَلَا يَسْتَظِلَّ وَلَا يَتَكَلَّمَ وَيَصُومَ فَقَالَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ مُرْهُ فَلْيَتَكَلَّمْ وَلْيَسْتَظِلَّ وَلْيَقْعُدْ وَلْيُتِمَّ صَوْمَهُ

Hadith on Worship: Muslims should worship moderately without harming their health

Anas ibn Malik reported: The Prophet, peace be upon him, entered the mosque and saw a rope between two pillars. He asked, “What is this rope?” They said, “This rope is for Zainab who uses it when she becomes tired during prayer.” The Prophet said, “Do not use it. You should pray when you have energy, but if you feel tired you should sit down.”

Abdullah رضى الله عنه reported: On the day he returned from the Battle of Ahzab, the Messenger of Allah صلى الله عليه وسلم made for us an announcement, “Nobody will pray his Zuhr (afternoon) prayer except in the vicinity of Banu Qurayza.” Some people, being afraid that the time for prayer would expire, said their prayers before reaching Banu Qurayza. Others said, “We will not say our prayer except where the Messenger of Allah صلى الله عليه وسلم has ordered us to pray, even if the time expires.” The Messenger of Allah did not blame anyone from the two groups.
