Sunnah Hadith
• Dusting the bed before sleeping
Authentic
إِذَا أَرَادَ أَحَدُكُمْ أَنْ يَنَامَ فَلْيَنْفُضْ فِرَاشَهُ بِدَاخِلَةِ إِزَارِهِ فَإِنَّهُ لَا يَدْرِي مَا خَلَفَهُ عَلَيْهِ
Idha arada ahadukum an yanama falyanfud firashahu bi dakhilati izarihi...
"When one of you goes to sleep, let him dust his bed with the inner corner of his lower garment, for he does not know what came onto it after him."
