Hadith 4531

(حديث مرفوع) حَدَّثَنَا عَبْدُ الرَّحْمَنِ ، حَدَّثَنَا مَالِكٌ ، عَنْ نَافِعٍ ، عَنِ ابْنِ عُمَرَ ، أَنّ النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ " نَهَى عَنْ تَلَقِّي السِّلَعِ حَتَّى يُهْبَطَ بِهَا الْأَسْوَاقُ ، وَنَهَى عَنِ النَّجْشِ ، وَقَالَ : لَا يَبِعْ بَعْضُكُمْ عَلَى بَيْعِ بَعْضٍ " . (حديث موقوف) (حديث مرفوع) " وَكَانَ إِذَا عَجَّلَ بِهِ السَّيْرُ ، جَمَعَ بَيْنَ الْمَغْرِبِ وَالْعِشَاءِ " .
It is narrated from Sayyiduna Ibn Umar (may Allah be pleased with them both) that the Noble Prophet (peace and blessings be upon him) forbade meeting traders before they reach the market and from deceptive sales, and that none of you should sell over the sale of his brother. And when the Noble Prophet (peace and blessings be upon him) was in a hurry during travel, he would perform a symbolic joining (jam‘ suri) between Maghrib and Isha prayers.
