BAYHAQI 11651:
from Abū ʿAbdullāh al-Ḥāfiẓ —
[Machine] "From the Prophet ﷺ: A man should not compete with his brother in bidding, nor propose to his brother's proposal, and do not dispute with one another, and do not trade by casting stones. And whoever hires a worker, let him inform him of his wage."
البيهقي ١١٦٥١:
عن ابو عبد الله الحافظ —
عَنِ النَّبِيِّ ﷺ لَا يُسَاوِمِ الرَّجُلُ عَلَى سَوْمِ أَخِيهِ وَلَا يَخْطُبْ عَلَى خِطْبَةِ أَخِيهِ وَلَا تَنَاجَشُوا وَلَا تَبَايَعُوا بِإِلْقَاءِ الْحَجَرِ وَمَنِ اسْتَأْجَرَ أَجِيرًا فَلْيُعْلِمْهُ أَجْرَهُ كَذَا
