A small thing with an instruction attached
One of the more everyday pieces of guidance in the collections.
التَّثَاؤُبُ مِنَ الشَّيْطَانِ، فَإِذَا تَثَاءَبَ أَحَدُكُمْ فَلْيَرُدَّهُ مَا اسْتَطَاعَ، فَإِنَّ أَحَدَكُمْ إِذَا قَالَ هَا. ضَحِكَ الشَّيْطَانُ
Yawning is from Satan. So when one of you yawns, let him restrain it as much as he can.
The full narration
Narrated Abu Huraira:The Prophet (ﷺ) said, "Yawning is from Satan and if anyone of you yawns, he should check his yawning as much as possible, for if anyone of you (during the act of yawning) should say: 'Ha', Satan will laugh at him
