[Machine] A necklace with the names of Allah, may they be destroyed, was lost, so the Messenger of Allah ﷺ sent some of his companions to look for it. They were overtaken by the prayer, so they prayed without performing ablution. When they came to the Prophet ﷺ , they complained about it to him. Then the verse of tayammum was revealed. Usaid ibn Hudair said, "May Allah reward you with goodness! By Allah, never has an affair been revealed to you except that Allah makes a way out for you from it and brings blessings to the Muslims through it."  

قِلَادَةً مِنْ أَسْمَاءَ فَهَلَكَتْ فَأَرْسَلَ رَسُولُ اللهِ ﷺ نَاسًا مِنْ أَصْحَابِهِ فِي طَلَبِهَا فَأَدْرَكَتْهُمُ الصَّلَاةُ فَصَلَّوْا بِغَيْرِ وُضُوءٍ فَلَمَّا أَتَوِا النَّبِيَّ ﷺ شَكَوْا ذَلِكَ إِلَيْهِ فَنَزَلَتْ آيَةُ التَّيَمُّمِ فَقَالَ أُسَيْدُ بْنُ حُضَيْرٍ جَزَاكِ اللهُ خَيْرًا فَوَاللهِ مَا نَزَلَ بِكَ أَمْرٌ قَطُّ إِلَّا جَعَلَ اللهُ لَكِ مِنْهُ مَخْرَجًا وَجَعَلَ لِلْمُسْلِمِينَ فِيهِ بَرَكَةً  

[Machine] I heard the Messenger of Allah ﷺ saying, "Whatever I have forbidden you from, avoid it, and whatever I have commanded you with, do as much of it as you can. Verily, those who were before you were destroyed due to excessive questioning and differing over their prophets."  

سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ مَا نَهَيْتُكُمْ عَنْهُ فَاجْتَنِبُوهُ وَمَا أَمَرْتُكُمْ بِهِ فَافْعَلُوا مِنْهُ مَا اسْتَطَعْتُمْ فَإِنَّمَا أَهْلَكَ الَّذِينَ مِنْ قَبْلِكُمْ كَثْرَةُ مَسَائِلِهِمْ وَاخْتِلَافِهِمْ عَلَى أَنْبِيَائِهِمْ  

Abu Musa said to ʿAbdullah bin Masʿud, "If one does not find water (for ablution) can he give up the prayer?" ʿAbdullah replied, "If you give the permission to perform Tayammum they will perform Tayammum even if water was available if one of them found it cold." Abu Musa said, "What about the statement of ʿAmmar to ʿUmar?" ʿAbdullah replied, "ʿUmar was not satisfied by his statement." (Using translation from Bukhārī 345)   

عَبْدُ اللهِ نَعَمْ إِنْ لَمْ أَجِدِ الْمَاءَ شَهْرًا لَمْ أُصَلِّ لَوْ رَخَّصْتُ لَهُمْ فِي هَذَا كَانَ إِذَا وَجَدَ أَحَدُهُمُ الْبَرْدَ قَالَ هَكَذَا يَعْنِي التَّيَمُّمَ وَصَلَّى قُلْتُ وَأَيْنَ قَوْلُ عَمَّارٍ لِعُمَرَ قَالَ إِنِّي لَمْ أَرَ عُمَرَ قَنَعَ بِقَوْلِ عَمَّارٍ
