That the Messenger of Allah ﷺ said: "Three will not be spoken to by Allah on the Day of Judgement, nor will they be purified, and for them is a painful torment: A man that gave a pledge to an Imam, and if he gives to him he fulfills it, and if he does not give to him he does not fulfill not fulfill it."  

رَسُولُ اللَّهِ ﷺ ثَلاَثَةٌ لاَ يُكَلِّمُهُمُ اللَّهُ يَوْمَ الْقِيَامَةِ وَلاَ يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌ رَجُلٌ بَايَعَ إِمَامًا فَإِنْ أَعْطَاهُ وَفَى لَهُ وَإِنْ لَمْ يُعْطِهِ لَمْ يَفِ لَهُ
