Narrated 'Aisha:

That she borrowed a necklace from Asma' and it was lost. Allah's Apostle sent some of his companions to look for it. During their journey the time of prayer was due and they prayed without ablution. When they returned to the Prophet they complained about it. So the Divine Verse of Tayammum was revealed. Usaid bin Hudair said (to 'Aisha), "May Allah reward you handsomely. By Allah, whenever you have a difficulty, Allah took you out of it and brought with it, a Blessing for the Muslims."

حَدَّثَنَا عُبَيْدُ بْنُ إِسْمَاعِيلَ، حَدَّثَنَا أَبُو أُسَامَةَ، عَنْ هِشَامٍ، عَنْ أَبِيهِ، عَنْ عَائِشَةَ ـ رضى الله عنها أَنَّهَا اسْتَعَارَتْ مِنْ أَسْمَاءَ قِلاَدَةً فَهَلَكَتْ، فَأَرْسَلَ رَسُولُ اللَّهِ ﷺ نَاسًا مِنْ أَصْحَابِهِ فِي طَلَبِهَا، فَأَدْرَكَتْهُمُ الصَّلاَةُ، فَصَلَّوْا بِغَيْرِ وُضُوءٍ، فَلَمَّا أَتَوُا النَّبِيَّ ﷺ شَكَوْا ذَلِكَ إِلَيْهِ، فَنَزَلَتْ آيَةُ التَّيَمُّمِ. فَقَالَ أُسَيْدُ بْنُ حُضَيْرٍ جَزَاكِ اللَّهُ خَيْرًا، فَوَاللَّهِ مَا نَزَلَ بِكِ أَمْرٌ قَطُّ إِلاَّ جَعَلَ اللَّهُ لَكِ مِنْهُ مَخْرَجًا، وَجَعَلَ لِلْمُسْلِمِينَ فِيهِ بَرَكَةً.
