Abu Umama said, "Shaytan comes to one of you in bed after his family has covered him and wished him good night. He throws sticks, stones or other things on him to make him angry with his family. When he feels that, he should not get angry with his family.' He said, 'It is part of the work of Shaytan.'"  

إِنَّ الشَّيْطَانَ يَأْتِي إِلَى فِرَاشِ أَحَدِكُمْ بَعْدَ مَا يَفْرِشُهُ أَهْلُهُ وَيُهَيِّئُونَهُ فَيُلْقِي عَلَيْهِ الْعُودَ أَوِ الْحَجَرَ أَوِ الشَّيْءَ لِيُغْضِبَهُ عَلَى أَهْلِهِ فَإِذَا وَجَدَ ذَلِكَ فَلاَ يَغْضَبْ عَلَى أَهْلِهِ قَالَ لأَنَّهُ مِنْ عَمَلِ الشَّيْطَانِ
