When a person bargains for a particular commodity, then another person comes and bargains for that commodity, it is not permissible.
Abu Hurairah (RA.) reported Allah's Messenger (peace be upon him) as saying: "A Muslim should not purchase (in opposition) to his brother."
[Sahih Muslim, Hadith No. 1515 a] .
عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " لاَ يَسُمِ الْمُسْلِمُ عَلَى سَوْمِ أَخِيهِ " .
[صحيح مسلم ، رقم الحديث : ١٥١٥]
