TABARANI 798:
from Abū Umāmah —
[Machine] I heard the Messenger of Allah ﷺ saying, "Whoever unjustly withholds the rights of a Muslim, Allah will forbid Paradise for him and make the Hellfire obligatory for him." Then, a man stood up and asked, "Even if it is something small?" The Prophet ﷺ replied, "Even if it is a branch from a date palm."
الطبراني ٧٩٨:
عن ابو امامه —
سَمِعْتُ رَسُولَ اللهِ ﷺ يَقُولُ «مَنِ اقْتَطَعَ بِيَمِينِهِ حَقَّ امْرِئٍ مُسْلِمٍ حَرَّمَ اللهُ عَلَيْهِ الْجَنَّةَ وَأَوْجَبَ لَهُ النَّارَ» فَقَامَ رَجُلٌ فَقَالَ وَإِنْ شَيْئًا يَسِيرًا؟ فَقَالَ النَّبِيُّ ﷺ «وَإِنْ قَضِيبًا مِنْ أَرَاكٍ»
