Narrator:Buraydah
وَعَن بُرَيْدَة قَالَ: كَانَ النَّبِيُّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ إِذَا دَخَلَ السُّوقَ قَالَ: «بِسْمِ اللَّهِ اللَّهُمَّ إِنِّي أَسْأَلُكَ خَيْرَ هَذِهِ السُّوقِ وَخَيْرِ مَا فِيهَا وَأَعُوذُ بِكَ مِنْ شَرِّهَا وَشَرِّ مَا فِيهَا اللَّهُمَّ إِنِّي أَعُوذُ بِكَ أَنْ أُصِيبَ فِيهَا صَفْقَةً خَاسِرَةً» . رَوَاهُ الْبَيْهَقِيُّ فِي الدَّعَوَاتِ الْكَبِير
Buraida reported that when the Prophet entered the market he said, “In the name of God. O God, I ask Thee for the good of this market and the good of what it contains, and I seek refuge in Thee from its evil and the evil of what it contains. O God, I seek refuge in Thee lest I get a bad bargain in it.” Baihaqi transmitted it in [Kitab] ad-Da‘ awat al-kabir.
