إِذْ يُغَشِّيكُمُ ٱلنُّعَاسَ أَمَنَةًۭ مِّنْهُ وَيُنَزِّلُ عَلَيْكُم مِّنَ ٱلسَّمَآءِ مَآءًۭ لِّيُطَهِّرَكُم بِهِۦ وَيُذْهِبَ عَنكُمْ رِجْزَ ٱلشَّيْطَٰنِ وَلِيَرْبِطَ عَلَىٰ قُلُوبِكُمْ وَيُثَبِّتَ بِهِ ٱلْأَقْدَامَ
When He made the slumber fall upon you as a reassurance from him and sent down water from the sky upon you, that thereby He might purify you, and remove from you the fear of Satan, and make strong your hearts and firm (your) feet thereby.

Chapter: About Jarir bin ‘Abdullah Al-Bajali رضي الله عنه
Jarir bin 'Abdullah narrated:
There was a house called Dhul-Khalasa in the Pre-lslamic Period and it was also called Al-Ka'ba Al-Yamaniya or Al-Ka'ba Ash-Shamiya. Allah's Messenger (ﷺ) said to me, "Will you relieve me from Dhul-Khalasa?" So I left for it with 150 cavalrymen from the tribe of Ahmas and then we destroyed it and killed whoever we found there. Then we came to the Prophet (ﷺ) and informed him about it. He invoked good upon us and upon the tribe of Ahmas.
