Bahz bin Hakim narrated from his father that his grandfather said: "No man comes to his Mawla and asks him for something from the surplus of what he has, and he withholds it from him, but on the Day of Resurrection a bald-headed Shuja'a [1] will be called to him and will be licking the surplus that he withheld."

أَخْبَرَنَا مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى، قَالَ حَدَّثَنَا الْمُعْتَمِرُ، قَالَ سَمِعْتُ بَهْزَ بْنَ حَكِيمٍ، يُحَدِّثُ عَنْ أَبِيهِ، عَنْ جَدِّهِ، قَالَ سَمِعْتُ رَسُولَ اللَّهِ صلى الله عليه وسلم يَقُولُ " لاَ يَأْتِي رَجُلٌ مَوْلاَهُ يَسْأَلُهُ مِنْ فَضْلٍ عِنْدَهُ فَيَمْنَعُهُ إِيَّاهُ إِلاَّ دُعِيَ لَهُ يَوْمَ الْقِيَامَةِ شُجَاعٌ أَقْرَعُ يَتَلَمَّظُ فَضْلَهُ الَّذِي مَنَعَ " .
