The Prophet ﷺ said, "Wretched is the slave of the Dinar, the slave of the dirham, and the slave of the fine garment. If he is given, he is pleased, and if he is not given, he is angry. Wretched and ruined may he be, and if he is pricked by a thorn, may it not be removed.Blessed is the servant who holds the reins of his horse in the cause of Allah, with his hair disheveled and his feet covered in dust. If he is assigned to stand guard, he stands guard, and if he is assigned to the rear, he stays at the rear. If he asks permission to enter, he is not granted it, and if he intercedes, his intercession is not accepted."
عن النبي ﷺ قال: تعس عبد الدينار، وعبد الدرهم وعبد الخميصة، إن أعطي رضي، وإن لم يعط سخط، تعس وانتكس، وإذا شيك فلا انتقش. طوبى لعبد آخذ بعنان فرسه في سبيل الله أشعث رأسه مغيرة قدماه إن كان في الحراسة كان في الحراسة، وإن كان في الساقة كان في الساقة، إن استأذن لم يؤذن له، وإن شفع لم يشفع.
Bukhari narrated it in Jihad and Sir (2887), from Amr (he is Ibn Marzuq), Abdul-Rahman bin Abdullah bin Dinar told us, from his father, from Abu Salih, from Abu Hurairah, and he related it.His saying, "If he is pricked by a thorn, let him find no one to draw it out," means, if a thorn strikes him, he finds no one to remove it for him with tweezers.
