"Do not meet the traders on the way, and whoever meets any of them and buys from him, the vendor has the choice of annulling the transaction when he comes to the marketplace.'' (Using translation from Ibn Mājah 2178)
قَالَ رَسُولُ اللهِ ﷺ لَا تَلَقَّوْا الْجَلَبَ فَمَنْ تَلَقَّى مِنْهُ شَيْئًا فَصَاحِبُهُ بِالْخِيَارِ إِذَا أَتَى السُّوقَ
